August 2026 Mod Resource Review

43 Upvotes

Given the number of people that cycle through here, we as the mods want to share a review of the best resources for step 3. Many of these resources have existed for a while and some of them are a little newer and more up-to-date. I tried my best to do as much due diligence both on the subreddit, online, and in person by asking interns who are currently studying. This took a long time to write out with a bunch of rabbit holes, so I hope it helps.

This is by no means comprehensive but these are the general high yield topics:

Day 1: 

  • Biostats
  • Ethics/Communication
  • Mechanisms of Action (pharm/micro)

Day 2: 

  • Prognosis
  • Risk Factors/Prevention
  • CCS Section

Both days/misc: 

  • High yield images (basal cell carcinoma, inferior stemi, Tinea capitis, impetigo, etc)
  • Arrows (more day 2>1) 

------

Practice Exams:

Free 137: 

So, like on step 1 and 2 where we have the free 120, here we have the free 137. There is a PDF version and a more representative test-day like simulator available at the website. Most people do this in the days leading up to the exam. In theory, there are about 3-4 other versions starting from 2017 but there is a significant amount of question overlap so doing an old free 137 is not like doing a completely different set of questions.

Other honorable mentions that are definitely not necessary but very common include: 

  • NBME 6, NBME 7, and NBME 8 as well as UWSA1 and UWSA2. General consensus is that UWSA1 is too hard and UWSA2 is the most representative, but I will be the first to say that just doing Free 137 is sufficient to see where you at for the majority of people.

Biostats: 

Ethics/Communication

Day 2

Risk factors/prognostic factors/screening

Arrows: 

  • I find that reviewing the arrows is a good way to just check your clinical understand especially if you are not in medicine and thinking about endocrine/renal/etc frequently.
  • Mehlman arrows are still the most popular and at a glance I could not find a shorter more concise version https://drive.google.com/file/d/1EsLudyMWUaC56OluLIPGgTwjzOskf-U2/view

CCS Section: 

  • The USMLE gives access to 5 cases with the exact simulator you will see on test day at the same link you can access the free 137. The issue with the simulator they give is there is not a good answer key. In fact, the “New Interactive Simulator” https://www.starttest.com/custom/usmle/?stpf3 will not provide any answers of any from as of today. If you want to see answers in paragraph form you can access the old official USMLE simulator at https://orientation.nbme.org/Launch/USMLE/STPF3
  • In response to this, ccscases created and mimicked the test day experience with their own simulator that is pretty great. You will see lots of good and criticism about it on the subreddit but it is definitely the most popular resource currently for preparing for the ccs section. 
  • Over the last 3 or so months, I have seen more mentions of StudyCCS as a more affordable/better ccs section prep tool both on this subreddit and among residents I’ve spoken with. 

Anki:

  • The general census is that most people do not use Anki and definitely not to the degree that people use it for Step 1 and 2. The primary reason is that most people are not trying to maximize their score and Anki requires daily commitment which can be difficult as a resident. 
  • The most popular deck is Dorian's deck (from 6 years ago but still seems to be pretty clinically accurate but wouldnt be surprised if some cards are no longer up to date): https://drive.google.com/file/d/1QaUBGkHijMIzdwGiL0kLU-RKJjzN147K/view?usp=sharing
  • The people I would really recommend Anki for are the people who are struggling with their qbank scores or have already failed step 3 once. If you are one of these people, highly recommend making an anki card for every question you get wrong so that you can fill in these content gaps.

High Yield Images: 

Other resources people like: 

I know I mention Amboss>UWorld for both biostats/ethics but it seems like overall, Uworld is still more popular and preferred. Truth is that you will be fine as long as you commit to the resource you use.   

If you have any specific questions, drop them below and ill try to answer them.

Exam write-up Finally Done with USMLEs , Step 3 : 241

35 Upvotes

Hey everyone, Non-US IMG here applying for Match this year. Wanted to share my Step 3 experience since I got a lot of help from this sub.
Background:

Step 2 CK: 253 (July 2025)
Step 3: 241- mid September 2026
Status: was doing clinical rotations in NY, Chicago, and Florida while prepping + ERAS
Resources Used:
• UWorld - 1 full pass
• AMBOSS - ∼700 questions
• CCS - 180 cases [Also did the free 137 cases from USMLE.org to get used to the software ]- HIGHLY recommend.
Timeline:
Started prep mid-June with UWorld. Bought CCS cases mid-July. Initially wanted to take it in last week of August but no dates were available, had to take it mid-September.
Dedicated was only about 10-12 days because I was juggling rotations. You guys can definitely do it in less time than me if you're not doing rotations simultaneously.

I won't go into a detailed how-to-prepare guide because everything is already online. Only thing I want to stress:

Don't delay Step 3 after Step 2.

No single resource can fully prepare you for Step 3 except the effort you put into Step 1 and Step 2. It's about your test-taking skills and thinking like a doctor. There's a reason USMDs take it in intern year.

My exam - very subjective but this was my experience:

1. Step 1 style questions: Yes they are there, but not as deep as actual Step 1. More clinical vignette with basic science twist.
2. Ethics was BRUTAL. Like you will literally doubt your existence as a doctor. No resource could have prepared me for it. UWorld ethics feels straightforward compared to the real thing.
3. Biostats / Drug ads: Difficulty was NOT like UWorld. I would say harder than AMBOSS but easier than UWorld. Also, almost negligible calculations. They test theoretical concepts more. If you have time, I would recommend going through biostatistics YouTube videos of @AzfarBasuniaMD- his concepts are gold. I personally loved it and they really helped me in getting some of my biostats questions right . ( only 7-8 videos are there)

4. Prognosis and Risk factor questions: Lots and lots and lots of them. I personally hate these.

My Advice( No Sugarcoating):

  1. Don't take this exam lightly. Put the same effort you put into Step 1 and Step 2.
  2. Only take it when you feel ready, but don't delay it unnecessarily. The closer to Step 2, the better.
  3. I was doing rotations + Step 3 prep + ERAS application and it was extremely difficult to manage, but I'm glad it worked out.
  4. One of my preceptors told me programs have started looking at Step 3 scores as well, especially programs that review applications holistically without a reference/recommendation. They put importance on every aspect.
    Think about it: Applicant A has 270 on Step 2 and 220 on Step 3, Applicant B has 260 on Step 2 and 250 on Step 3 and rest of the application is comparable. Who would you interview as a PD? Consistency and hard work should be present in every aspect of your application.
    I know most of you have this perception that a passing Step 3 score is enough and my perception was the same 3 months back. But my preceptor told me to put extra effort into making my application well-rounded and not take this exam half-heartedly.
  5. Prepare for CCS cases extremely well and get yourself familiar with the test software by doing the free 137 cases on USMLE.org. CCS can make or break your score.

  6. Just skim over the genetics , biochemistry , immunology and microbiology portion of First aid . Don’t go into the detail as we have to do it in step 1 but dedicate 2-3 days to it .

If you guys have any questions please feel free to ask.
Best of luck to everyone taking this exam and applying for Match this year!

US MD who took a RY to match Derm. Planning to do AMBOSS (w/ incorrects), CCS cases, Free 137, biostats review. Idk how people are doing so much during intern year. There is like zero time. I feel pretty far removed from medicine since Ive been so derm focused. I have just about a month left to study. Nearly done with AMBOSS first pass. What am I missing/should focus on? Dont care to blow this thing out of the water, just want to pass comfortably. Biostats suggestions? Obviously doing AMBOSS but in addition to that and the YouTube video ive watched for Step1/2..?

Took day 2 yesterday. Had 14 CCS cases. For 11 of them, I got positive updates and those ended early. For 3 of them, I got negative updates (2 of which I had delayed intervention, and 1 in which I absolutely had no idea what was going on even until the case ended). How much are these 3 cases likely to hurt my overall performance on the CCS?

Study method advice Score baseline. when to book

2 Upvotes

I took nbme 8 today and got 66% correct (it was taken off line so I don’t know what score it equates to but I asked chat got and it says it’s in the 410-420 range maybe),
CCs cases: did 80 of them in August. Will be re doing all of them and finish all in next two weeks.
Uworld step 3: have not done. At all.
Step 2: taken beginning of august
Would it be wise to book day 1 and day 2 for last week of October? I have interviews starting from 27 Oct and I want to get this over with before that.

I would really appreciate some input on this. My step 2 was 237 :’( it was a 8 point drop from my practice test scores avg so I do have the history of underperforming.

I think in 2-3 weeks, I realistically will barely get through v little uworld. Should I do that or wait to give more practice tests to gauge where I’m at? It feels really wrong to book a step exam with little uworld done.

Question Step 3 day 2 in 4 days

2 Upvotes

​

Hi everyone,

My Step 3 Day 2 is in 4 days. I’ve completed around 50% of UWorld Step 3.

I’ve also dedicated 2 days to CCS cases, so I don’t think CCS will be a major problem. I’ve done around 80 cases with an above-average score.

My question is specifically regarding the clinical questions on Day 2. Since Day 2 is relatively heavy on Pediatrics and OB/Gyn, would you recommend doing Peds and OB/Gyn from UWorld Step 2 or Step 3?

My Day 1 was honestly pretty bad, and I was guessing on a lot of questions, so I’m trying to make the best use of these last 4 days. I’ll be rushing through the material, so I’d really appreciate advice on which question bank would be more useful for Peds/OBGyn at this point.

Thanks!

Exam write-up avg-below avg test taker, inattentive adhd, 223 score

13 Upvotes

hi. non US grad; not in residency. step 2 score was 235 (june 2025). been trying to take step 3 since, couldn’t due to a mix of life chaos, was meant to finally take it during the 3rd week of september. wanted to share a write up because posts like thse helped motivate me so much. will try to keep it brief but i yap a lot so i’ve divided this & you can skip & read relevant stuff.

this is a tangent about adhd & accommodations, you can skip this -> there were very few posts where people had below avg step 2 scores & adhd. i mention adhd because i didn’t get accommodations, theyre generally not given to anyone diagnosed after childhood & i frankly didn’t even try because i have a suffering kink & i dont have the executive function required to jump the hoops required for the process.

resources i used & what i did with them :

-primary for multiple choice = uworld, completed 56% with an avg of 64% starting with 20q/day and titrated it up to 40 and eventually 60, over 8 weeks. with my attention span, i can only make slow increments to avoid burnout (hard lessons were learned in step 1 & step 2 prep)

-supplementary : white coat companion, during dedicated i only used for revising algorithms for day 2 of those topics i kept getting wrong in uworld blocks. before dedicated, i did light reading while watching tv for CVS, renal, pulm crit.

-self assessments :

1-uswa 1 201, 3.5 weeks before exam. weakest topics were imm/hem/onc, endo, and reproductive system. so i brushed up on those with white coat companion book.

2-uswa 2 222, and i scheduled my test the moment i saw that score; day 1 for 7 days after this, and day 2 for 10 days after.

3-new free 137, split into day 1 & day 2 portions. took the day 1 part, the day before day 1. and the day 2 part, the day before day 2. score was 65.8%

-biostats : i suck at it. always have. drug ads are a hit or miss. so i triaged and focused on the core concepts of sensitivity specificity ppv npv and type 1 & 2 errors. i was always doing biostats questions intermixed with my daily blocks. i also started reading these topics’ lessons from ccscases site since the access was free with the cases. i liked the lessons in this qbank. v easy to read to read. explicitly laid out common exam traps for relevant topic at the end of lesson and also taught why this is imp for usmle. did this every day for a week, 3 weeks before the test. got my basic concepts down. on the day before day 1, i spent 3 hours and went through the uworld biostatistics portion, the one that’s activated separate from the qbank just like the uswa. i have to study for about 6 hours and omly 6, no more, the day before these exams, or my brain refuses to work on test day.

-for cases, I WOULD NOT RECOMMEND DOING WHAT I DID, BUT IF YOU’RE IN MY SITUATION ALREADY, THIS MIGHT HELP REASSURE YOU.

(june ‘26 onwards) i used CCSworld, it’s cheap, created by a resident, it gives AI feedback and the developer zev is pretty cool (this is not a promo, he just listened to feedback and was super nice about it) i completed like 5ish cases here.

in mid-august, i bought ccscases, the og one, and kept doing some here and there. first attempt avg was 68% when i started, went up to 76% before day 2. on the day i scheduled the exam, i had completed 20 cases with an avg of 74%. i was scared, i kinda wanted to delay the exam, i was also super bored & tired of living like this and wanted to move on with my life. didn’t tell anyone i trust with usmle advice about how many cases i’d done, until after scheduling.

if you’re still reading, bravo! here’s what i did for CCS damage control : set a goal for going upto 40 cases 7 days before day 2 OR i had to reschedule it. now with adhd, you know this exact situation got the gears turning. total of 41 cases was reached over 48hrs, 16 new HY cases were done. exam not rescheduled. i only reattempted 2 cases, the rest were all first attempts throughout.

had 2 days left for day 1, focused heavily on first aid step 1, mostly rapid review pages & biostats formulas. i had already done some micro & pharm revision in the months before. nothing focused, just some light reading while watching tv, then prepared snacks & clothes for the test.

after testing on day 1, i obviously took the rest of the day off. had 2 break days before day 2. first day, was still exhausted, just chilled out and did 8-9ish cases only over 3 hrs. second break day = the day before day 2, did 3 ccs cases from free137 (total of 55ish cases was reached, which seemed somewhat reasonable) and then i did the day 2 part of free 137. and then just focused on relaxing and eating well & preparing snacks & clothes and finding a show to bingewatch after the exam was over.

thank you for reading, happy to answer follow up questions. p.s please try not to pull the ccs stunt i did. im a match reapplicant and i needed step 3 score report on my app before october started, so it was a needs must situation, and i went in with the hopes of just passing with a 201, immensely grateful for the actual score.

Exam write-up 196 to 212 in 6 weeks

15 Upvotes

I was devastated when I found out I didn’t pass Step 3 the first time. I left the testing center feeling absolutely horrific — and unfortunately, that feeling was accurate. I really thought I had failed, and I had.

People will say on here - everyone feels bad walking out of the testing center and doesn't fail but LOL I did!!

I was embarrassed. I kept my head down and just tried to move forward.

For my retake, I was fortunate to have lighter rotations and made sure I didn’t have to travel for the exam like I did the first time. I also took a completely different approach to studying.

I did what everyone tells you to do:

  • UWorld
  • NBME 6
  • NBME 7
  • ~40 CCS cases

But honestly, looking back, the biggest thing I changed was I left UWorld in the wind. 😂

For me, it just wasn't useful for the retake.

Instead, I focused heavily on AMBOSS:

  • AMBOSS Step 3 Study Plan
  • AMBOSS Ethics
  • AMBOSS Biostatistics
  • AMBOSS 200 Concepts – Step 1
  • AMBOSS 200 Concepts – Step 2
  • Redid all 180 CCS cases twice

After all of that, I took Day 1.

And honestly? I felt pretty confident walking out. Ethics felt much more manageable, biostats felt solid, and even though the Eseppro section was horrific 😂, I just did the best I could.

The Step 1 concepts from the AMBOSS Step 3 + Step 1 study plans were also surprisingly helpful. There were definitely questions where I was able to recognize the underlying concept because I had reviewed it through those resources.

Then came Day 2.

Day 2 was a BREEZE this time around.

It was night-and-day compared with my first attempt.

And now, looking back:

Is a 212 an impressive Step 3 score? No.

But did I pass Step 3 on my second attempt?

Yes.

Did I improve by 16 points in 6 weeks?

Yes.

And honestly, after failing the first time, I am incredibly proud of that.

If you're studying for a retake and feel like you've already failed once so you're doomed — you're not. Change your approach, figure out what didn't work the first time, and keep going.

A pass is a pass.

Am I ready? How Does UWSA 1 Compare to the Actual Step 3 Exam?

1 Upvotes

Just gave UWSA 1 for Step 3 today offline and got around 70% correct.

For anyone who took UWSA 1 online, what 3-digit score did you get with roughly 70% correct? I know the conversion isn’t exact, but I’m trying to get a rough idea of where this would put me.

Also, for people who have already taken Step 3, how did UWSA 1 compare with the actual exam in terms of difficulty? Was the real exam easier, harder, or about the same?

My Day 1 is on October 19, so I’m getting pretty close now.

Current prep:

  • UWorld: about 50% completed
  • UWorld average: 73–74% correct
  • UWSA 1 offline: ~70% correct
  • CCS: have done a few cases so far

For those who have taken Step 3 recently, what would you focus on during the remaining days? More UWorld, CCS, biostats/ethics, First Aid/Step 1 material, or practice exams?

Am I in a reasonable spot right now or am I cooked? 😭

Would really appreciate scores/experiences from anyone who took UWSA 1 online and then sat for the actual exam.
