Ok so long story short, I had really bad untreated adhd as a kid and basically floated through math my whole life, were talking 68.5 test/homework/quiz grades rounded up to 70 out of pity by my teachers my whole life. I failed out of college my freshman year at the age of 18 but somehow managed to pass algebra with a C through cheating before getting kicked out. I am now 22 and had some sort of life epiphany. I have all the motivation in the world and have completed most of my credits for an associates degree with a 3.4 except for my mathematics. I just took college algebra and I attacked it with all the energy I had but I still didn't succeed. I would study by myself and with tutoring and I still felt as if I was having trouble retaining any information by the time tests rolled around. I desperately want to become good at algebra but I cant afford to keep retaking and failing the course until I actually learn the material. I need some sort of structured way to learn and master algebra outside of the classroom before I retake the course. What is /sci recommendation?
