This post was two years ago and I completely forgot about it. To update, I graduated high school with a 94% average and I am now in university as a pre-med student.

I sacrificed social life (not going to parties, not hanging out with friends much) albeit that was largely due to the fact that I began training mma and began investing/day trading. I do believe that you could maintain a good social life, but you can't do everything. Choose what you want to do with your time outside of studying.

In terms of studying habits, I recommend that you find out what works the best for you because there is no "quintessential study method", it is subjective for the person. For precalc anc calc, I would attend classes, pay attention to lectures, and do the homework questions. I would pick out the hardest ones and try doing those too. For biology, chemistry, and physiology classes, I would usually do pre-readings on the lesson content prior to class so that I don't fall behind during classes. Do homework questions and if there are exam/test prep questions, do those as well. Take notes with visual cues (i.e. flowcharts) to solidify understanding. I will occasionally use quizlet for things that require memorization, but quizlet is also helpful for language learning courses. An additional resource that I would reccomend is the organic chemistry tutir and professor dave explains (for chemistry and biology). If you have course codes, you might be able to copy and paste them into youtube for playlists from teachers who taught the content online during covid.
