How to improve your skills in math?

I bought a bunch of math books, and read a couple pages every night, then at the end of a wk I would test myself on that stuff. plus I wrote a lot of notes in class so that if I hadnt been fully understanding I could go over the stuff without distractions

There's an abundance of ways to improve your skills in math.

The way I improve my skills is paying attention to my teacher and stop talking to friends. Ask questions if you don't understand. Do extra practice at home. And study for upcoming tests.
