What is the best way to use a textbook?
It's pretty straight forward for Humanity/Bio/Medicine textbooks.
>Scan through the Chapter
>go back and Read the Chapter
>Read it again if your Brainless ass can't understand the concepts.
>Use the summary to do your Flashcards or whatever bullshit you use to memorize shit.
But how do you Use Math/Physics/Chemistry Textbooks?
For example, I'm done doing the Humanities and Bio reading for an Entrance Exam, so today I started with the Chemistry textbook, They have the Summary, PLUS key equations, and like OTHER 100 exercises per chapter.

What should I do with the last 2? should I do all the exercises? Should I do only the ones that have the answer in the back?
Should I memorize the Equations as I do with Parts of the body and that?
