Would like to obtain a Computer Science degree but suck at math. Is Khan Academy good enough?

Hello everyone,

I have a question regarding learning math. I want to obtain a Computer Science degree but I am terrible at math. My math competency level is in the middle school area. I want to attend college starting in August of this year, and I am currently working on improving my math skills, starting with prealgebra. I plan to dedicate 6+ hours a day to learning math. Is Khan Academy good enough for me to become college ready, or should I use a different resource?
