Math is a game...you don't rehearse it to understand nor read it like a casual book, rather you choose one topic to deal with for 3 days or something, then understand the principles, then enjoy making questions on it...lemsale, choose polynomial functions and read the principle for 2 to 3 hours while taking out notes. then, for 3 days, try doing different questions starting from ones that are on the book that taught you the principle to questions that are on the internet...try to solve each...not with a stress or anything, make it like a game...like a sudoku card that you walk with and solve.
