you are already in some place in math.
figure out ur improvement areas and start solving problems. You may also ask your doubts ...

Do you feel like you can explain every single question in the tests you have completed to someone else?
Try actually doing this if possible, or try doing it out loud if there's no one who wants to hear the explanations.

I very often see students who "complete" tests meaning they answer all the questions, but they rarely go back and make sure that they can fully explain every single question, in case they see it again.

Create a review sheet that asks the following for all questions;

What is the concept(s)?
What word or phrase triggered that concept(s)?
What is the consistent way you use to solve a problem with that concept?
What was the tricky part of the test or something new you learned (this can either be mathmatical or test takign strategy/ psychology?

After you have done that then redo the problem with the concepts.
