How to study?

Hi, how much time do you guys spend on solving EOC questions. What do you do when you get stuck on a question and you have read the explanation but it still doesn’t sink in. Do you move on immediately or do you keep trying for a little while? I am asking this because I am way behind on my schedule and I have too many questions to solve. So I was wondering if you guys could help me figure out how to go about it.

Hi, I spend usually 2 hours per day solving questions, when I find a question difficult to understand I read the part of the reading related to that question, If I don’t understand, I move on and come back next day, sometimes is a matter of clear your mind

Ok thank you.
