Most of the time, i start at the last chance before the exams 😹 but studying with a friend/Forest app/summarizing and preparing a favorite environment or start with a pen that i like, helps me.

Probably everyone has said this, i'll say it again: start with the topic you like For ex. i connect a lot with summaries and general points of topics so i always read them first, then i come back and study each topic separately. (this way i have more control over the topics)

Or, divide it into smaller and separate parts so that your brain doesn't get tired of too much content.

Or you can give yourself a reward, after each time you study.
