LOLLOOLL SHOULD HAVE LISTENED IN CLASS

you have a studyguide?

are you in school or uni?

Study with chatgpt.
Post questions of your book to chatGpt, tell him to justify, explain, do it with every single question, at the end of day tell him to post a summarize all your mistake.
Tell him to tell you 20-80, 20% of a subject that makes you learn about 80% of it.

You can do questions of any subject even if you never read about a specific subject, just do the ''reverse study'' using chatgpt.

Learn how to ask questions properly to it too.

I do not recommend you to study just "reading", focus into questions only, do reverse study = win.
Learn theory by questions using chatgpt.

If your book has no more questions, tell chatGpt to make similar questions based on what he just answered.

Tell him to make mnemonic if you need to memorize something.

If there's no more question to do, tell chatgpt to make new questions for you based on what he just answered.
Keep doing reverse study.

read your notes

Study something that is on the test then play a swift play, when ur done the swift play see if you remember everything you studied before the swiftplay, if you did that move on to something else that will be on the test if you dont remember then study it again and repeat the process

2 days is easily enough time. just start reading

use pomodoro technique, study 25-minute + 5 min rest
if you like music while studying you can search on youtube. this what i usually use :https://youtu.be/DXT9dF-WK-I
