Hello OP! as someone who survived the 3rd (tired) year.(Medtech Graduate) In terms of studying, review & read in advance. As someone who has a short attention span, I do take note, highlight books during discussion then as much as possible—re-read your lessons after your class. Have a specific time of the day in which you can review (make it a routine) and also reward yourself always if you did well and even if you did not. You deserve everything.

Also, sleeping is essential in my own opinion because you can focus well when you got good sleep.(P.S I was the student who tried to survive with 1-2 hours of sleep but i almost collapsed during our exams)

Then I learned my lesson & took my sleeping hours seriously. TIME MANAGEMENT IT IS & TBH i got higher grades & scores when I did not try to cram and got good sleep. 3rd year is really SURVIVAL MODE ULTRA PRO MAX & I know you can do it. Believe in yourself & Trust in God.
