How do you study for math

I really need to boost my math mark up, but ... how do you study math ? I'm in grade 10 btw
Ohh and exams are about 2 weeks from now :( and I'm under 50 -.- exam is worth 30% of my mark

The best way to study math is to do math. Do all the problems that your teacher did in class. Do all the problems you were assigned for homework. If you have access to old exams, do all those problems too. Do problems from your textbook that weren't assigned as homework. Do problems until you're dreaming about them. Do so many problems that you become confident that nothing they come up with will stump you. And then do them all again....

Definitely go over notes. Work out a few problems from the textbook. Go over quizzes and tests and try to work out problems you got wrong and figure out why you got them wrong in the first place, so that you don't make the same mistake. Good luck on your exam!

Going over anything that might be on the exam.
See if your prof and/or a tutor are available to help you do sample problems.
If not, be part of a group with students motivated to succeed - not just pass.

i'm not an expert but you can go through all the practices in your book. . . and if you don't understand some of them you could ask your teacher?
