Repetition is half of the learning process. You also need a reason. If they brain believes what you are doing is pointless towards your existence (a weird study in and of itself), then it will trigger boredom-defences and you won't learn, no matter how much you study.
You cannot force your brain to learn something it doesn't want to.
You can force yourself to sit down, do math homework and be better at, if not understanding the material, regurgitating the process on future assessments.
I might be biased on this because I love math, but it works for me for language classes. Also, it's worth noting that Setro posted a topic earlier this
week asking for math help and saying "I can't fail another math course." If you can't fail another math course, do the work. Not that hard.
