I hadn't finished my math prerequisites when I decided to enter university. I was missing 3 courses that would normally take 3 semesters. I finished the equivalency of 4 courses in 5 weeks using Khan Academy and crushed the aptitude tests.
I did that by studying every day for 3 hours. I always meant to study 4-5 hours per day, but I never managed that. I am now far ahead of my classmates in general algebra, because math is generally taught incorrectly, When you dive into it every day, it gets a thousand times easier because you don´t spend any time trying to remember vague concepts from last week, it's all fresh in your memory for you to stack up the pieces and build a solid foundation.
Set yourself a goal, find some way to test yourself, Khan academy will help you build an incredible mind for mathematics.
