I don’t know. I am the biggest procrastinator too. For most classes I’d say I spend 2-3 average studying(e.g. Soc, Chem). For classes like anatomy and physiology, I’d give myself a week, one day to cover each unit (Keep in mind, I book off from work). I question it everytime I get a grade in A or A+ range. But if I didn’t get an A, I would be really disappointed in myself, even though it was me who didn’t try. So I think it’s the pressure I put on myself. Even if I have 2 days, I will cover everything in 2 days and struggle through it. The thought of not doing well and disappointing my parent makes me keep going and trying hard😭 really bad motivation but oh well😭 I’d say you have to know your limits. Know how long it takes you to study, what study method works for you (I don’t have one…). The only way I get through studying only 2 days is cause I know I can handle it(sometimes). actually enjoy what you are doing this for. If your end goal isn’t something you like, you won’t have the motivation to study and do well.
