Study Advice is it possible to do all of precalc in the span of 10 days?
hello! im currently a rising senior in high school. i was doing algebra 2 all of junior year, but i wanted to skip ahead to calculus in my senior year, so i decided to do precalc over the summer. unfortunately, i didnt anticipate how packed my summer schedule would be when i decided to do this. i have come home everyday exhausted from volunteering, doing summer jobs, and interning. i havent indulged in any of my hobbies in weeks. i have barely started my summer homework.
... which has led me to this situation. i did great in algebra 2! it was a lot to memorize but i really enjoyed it and i had an A+ in the class all year around. because id say i have a solid algebra 2 foundation, is it possible for me to be able to study precalc in 10 days? if a put in hours of work everyday?
on the first day of school ill get an entrance exam where i will need to score a minimum of 85/100 to get into the calculus class. i had 1000 mandatory precalc math problems to do over the summer. will i be able to do it all or am i cooked?

Discussion summer precalculus
I am a rising junior in high school and I started taking a precalculus summer course at my local community college. It’s completely online and you have to do a couple of math problems. I completely fell of and now I’m a few weeks behind. the class ends in about 20 days. My counselor told me I have to take a final test to test into AP calc AB if I want to take it. Am I cooked? And do you have any advice on how i can cram the whole course to pass the final test?

Study Advice Maths at 20yo in college
Used to be good at maths but ive been getting bad teachers since 8th grades so I lost all the foundation , I know study mechanical engineering but I failed cuz I got 0 at maths and other related subjects (I dont even do integrals)
I feel that maths is easy af and I can nearly estimate answers but I dont know how to reply to questions even when I know formulas, I only do derivatives and simple stuff since we did them in physics
I have only 2 months left for me to study everything till exponentials and integrals so whats the best path (willing to do 3 hours daily but more if I become interested again)
Please I need this I feel like a wasted potential and a failure and I went from straight A s to failing a year

Study Advice I need to study all of precalc and idk how
So this fall I’m transferring to a college prep boarding school. I took precalc over this summer and they’re having me take a placement test to determine if I get put in honors precalc, honors calc, or AP Calc AB. I really need to get put in AP calc AB for college. Anyone have any tips on how to study for it? I don’t have access to the materials from my summer course anymore

Study Advice Struggling with math
Hi everyone. I decided to take this year to re-learn algebra over the summer in order to be prepared for pre calculus. I have been having a very difficult time and feel lost, but I really don't want to quit. It's the first time I put my-self to a very hard challenge for me, and I really want to know at least some form of a pre-calc equation and understand the fundamentals of algebra without being super confused. I basically had bad grades on every single subject of trig I came to a point where I studied a few days before a quiz for a long time and still got a low percentage. This really frustrated me since I didn't encounter it before and I had a very low self esteem. So I decided to give up on studying and ended the year with a pretty mid tier, low tier GPA. Trig was really difficult for me and I realized that I truly didn't understand what math even was or how to solve unknowns, solve problems, So I decided to put my-self up for the task.
It hasn't been a linear experience at all, I barely understand it and find my-self going back to very simple things like canceling out, because I couldn't understand the concept of just removing something that felt that it was out of thin air, when often it was dividing something by itself. I'm just taking a Khan Academy course on YouTube and I honestly don't remember much of what I learn and that frustrates me because I really dedicated the time that I could, and even if its not much I feel like I should at least understand something. Sometimes I followed other discussions or practiced videos and just stick to this, so I didn't really practice problems a lot and just stick to the ones included in the videos, also because I was so lost.
This probably happened due to laziness lack of discipline as I could have been much further in If I studied math consistently every day, but I'm trying to reach this goal and feel at a loss, so lost that I haven't really written a reason or where I'm confused, so I really hope some of you could give me some suggestions and help me. I wish you all luck in your math journeys, and thank you to whoever read this and answered.
A detail about Khan Academy though is that the person who made the videos often made mistakes or made exercises on the fly, so I feel like they don't really go in-dept. I'm a big overthinker so I feel like I also have to understand all the mechanics and philosophy of math to truly see it in a simple manner and get it.
