Okay, so I am 20 years old, did terrible in highschool mainly due to lack of motivation / not seeing the point. I left highschool with grade 11 math and had a whopping 52. Three years later I discovered I like math and seriously want to get to an advanced level. I started taking some remedial grade 10 stuff at a local college, doing very well and not feeling challenged enough. What I am asking for is some quality textbooks, reads and a possible mathematical sequence to follow for my studies, starting from the basics, algebra and geometry. Though I am doing well in a grade 10 remedial course, I definitely need a more mathematical understanding of things to go further. - Thanks to anyone that helps.
