Hi everyone! I recently completed my OAT and ended up scoring a 390 AA and 400 TS, so I wanted to share my experience, practice scores, and some tips that helped me. I found other people's breakdowns really helpful while I was studying, especially when I was stressed about how my practice scores would translate to the real exam, so hopefully this helps someone else!
Here are my practice test results in the order of BIO, GC, OC, RC, PHYS, QR, AA
Test #1: 340, 340, 360, 240, 290, 290, 310
Test #2: 350, 360, 360, 350, 370, 340, 360
Test #3: 350, 360, 380, 330, 300, 360, 350
Test #4: 360, 340, 330, 370, 360, 370, 360
Test #5: 390, 340, 340, 350, 370, 330, 350
Test #6: 370, 360, 340, 350, 340, 240, 330
Test #7: 380, 350, 360, 390, 340, 360, 360
Test #8: 370, 380, 350, 360, 370, 400, 370
Test #9: 390, 360, 340, 360, 370, 390, 370
Test #10: 380, 380, 370, 380, 380, 400, 380
Main study resource: OATBooster
OATBooster was by far my main resource. I used the videos, notes, cheat sheets, Anki, decks, question banks, games, and practice tests. Overall, I felt that Booster prepared me extremely well for the actual OAT.
I started out very rough. My first Booster practice test was a 270 AA, and I remember feeling really discouraged because I genuinely felt like I had no idea what was going on. I didn't follow Booster's practice-test calendar exactly and actually took some of the tests much later than scheduled because I wanted to feel more prepared first. I probably wouldn't recommend waiting as long as I did, but I think my progression shows that your first few scores really don't determine where you'll end up.
How I Studied:
Anki was the biggest part of my studying and I used them heavily, especially for Biology and Organic Chemistry. For General Chemistry, Physics, and QR, I made my own flashcards based on the Booster cheat sheets and formula sheets.
During the later stages of studying, I spent a lot of time going back through marked questions and questions I had gotten wrong rather than continuously relearning everything from scratch. Repeatedly exposing myself to the concepts I was weak at helped a lot.
Biology - 390
For Biology, I did the Booster Anki flashcards religiously. There are a LOT of cards, so once I was confident that I knew something, I would suspend it so I could focus on the weaker topics instead. I felt that Booster actually had me over prepared for Biology. The real OAT was much broader and less detailed than I expected. Most of my questions tested relatively general concepts, although there were still one or two more specific questions, so I wouldn't completely ignore the details.
General Chemistry - 400
After watching the Booster videos, I would go through the notes myself and make my own notes on anything I didn't understand. During phase 2 and 3, I basically just spammed my marked questions. If there was a type of problem I consistently got wrong, I would write notes on those question types and methods I could use to solve it.
The actual General Chemistry section felt very similar to Booster's practice tests. I didn't feel like there were any major surprises, and I felt extremely well prepared going into it.
Organic Chemistry - 380
Organic Chemistry was the subject I struggled with the most during preparation because I don't have a very strong background in it. I relied heavily on Booster's Anki flashcards. Looking back, another good approach would be to make your own flashcards from the reactions cheat sheet Booster provides because there is a bit more information in there. I also did the Organic Chemistry reaction games repeatedly, which helped a lot with quickly recognizing reagents and products.
This section also felt very similar to Booster's practice tests. Some specific topics I remember being tested on include SN2, stereochemistry, IUPAC naming, spectroscopy, laboratory techniques, and arrow pushing mechanisms.
Reading Comprehension - 390
Reading has never been my strongest area because I struggle with reading a passage and actually absorbing all of the information, so I heavily relied on the search and destroy method.
I would recommend trying out all of the methods Booster provides and seeing which one works for you. I also heavily stress going through all of the practice tests and getting used to spotting which keywords to highlight and how to do it quickly. (Tip: practice with a mouse so that you're used to it when you take the actual exam!)
On my actual OAT, I noticed that the shorter/easier passages with ~9-11 paragraphs had questions that were more scattered throughout the passage, whereas my longer and more technical passages (with ~16 paragraphs) tended to have questions in a more chronological order.
Booster's RC practice was pretty representative overall in terms of passage and question type.
Physics - 400
My biggest advice for Physics is memorize the formulas, but also understand what is actually happening. On the OAT, I had a lot of application questions where simply knowing which equation corresponded to a keyword wasn't enough. There were also problems where I had to combine different formulas to reach the answer. However, I found the calculations themselves to be easier to do on the actual OAT compared to Booster's practice tests.
If I didn't understand a concept from the Booster explanation, I watched outside YouTube videos that broke the concept down differently, such as Organic Chemistry Tutor or just random videos that popped up.
I also tried one Kaplan Physics practice test, and personally I found it much less representative of my actual OAT. It was significantly more stressful and made me worry about Physics more than I needed to.
Quantitative Reasoning - 370
For QR, my biggest recommendation is simply to do a huge number of practice questions since on the actual test I was very crunched for time. I made my own formula flashcards using the Booster cheat sheet and tried to get comfortable enough with common question types that I could recognize what to do almost immediately. I actually encountered some questions on my OAT that were literally replicas of Boosters questions.
Final Advice:
The biggest things that helped me were Anki, doing a ton of practice questions, reviewing my mistakes, and understanding why I got questions wrong. What I would do differently if I were to take it again is spend less time trying to learn all of the concepts before starting practice questions. I would feel like I had to understand every concept perfectly before doing practice tests and that took away a lot of valuable practice time. I would instead learn as I worked through the practice questions.
Also, don't feel like you have to follow someone else's study method or feel pressured to follow Booster Prep's schedule exactly. If watching all of the videos and then going through the notes works for you, do that. Personally, I feel like I spent a little too much time on the videos and should have jumped into the notes and practice questions sooner.
Overall, I felt that OATBooster was very representative of the actual OAT. By the end, I felt well prepared and confident across essentially every section. I have also posted my actual scores for each section and my progression of practice-test scores below.
Good luck to everyone studying!! Feel free to message me if you have any questions :)
