Math grade problem

[Alarba]

I'm at the last year of high school (aka last year before University) and I just received my first math test. I got 10 out of 20 which ridiculously low ( Finished my 2 previous years with 16 in 20. It's not that I dont understand what i'm learning nor a study problem ( Yeah i know i dont study much but i actually did alot of exercises for this test ), it's just that I do the test and then......I get a sh*tty grade. Advices?

 :ps: Still aiming to get a 20 out of 20 in atleast one test.

Mock Exams.

Yeah, do lots of practice papers...I've found a lot of marks are lost because the markers don't know the subject...they just go by the mark scheme. Answer not there: Won't get a mark.
Exam technique ftw.

I had a similar problem before, but I solved it. Here is how I solved it:
Look over all your mistakes in the test, then figure out what was wrong.
Correct EVERY mistake. Then tell your big brother/dad/mum to make you another math test.
Then keep practicing on your mistakes until you finally understand the principle.

If there is something you don't understand, then I prefer you to go to your dad/mum/big brother or even your teacher to get that solved. Or you can ask Google if none is available

 :ps: This strategy made me go from 3 to a 5. I am freakin' happy. (1 = fail ---- 6 = best grade )

in the 2 years before University at a school, usually people aged 15-18, our A Levels are graded slightly differently

A--B--C--D--E-------------------------------------U
Best                                                           Ungraded
