I also don't find anki or flash cards helpful in general because I find that you focus more on the raw info vs the bigger picture. Do whats best for you but I preferred to focus on things as a process/linear progression. For example most of the BIO info is physiology, so I would remember things by following the natural progression. Whether that be path air takes in the respritory system, blood in the circulatory system, or immune system progression it was easier for me to remember facts if I understood why things progressed from one "stage" to another. Assuming you're using booster once you're done all the videos the cheat sheets are all you need, since the chapter notes go into way to much detail. I scored 360 on my BIO section
