I'm a 33 year old self-taught software developer, that originally skipped college, who is starting at a local community college this fall with plans to transfer to Illinois for Computer Engineering.
I can't express how much your team and Mr Khan have helped me. In June I spent one to two hours a day watching videos and completing exercises to prepare for my schools placement exam. Starting from the beginning, not only did I refresh my memory but also learned essential concepts that my high school education did not cover. Thanks to your site I placed at the highest level my school will place an incoming freshmen for mathematics.
I'm looking forward to finishing off the last 4 exercises and hope to see more soon. I would be very nervous about both working and going to school full time, during my first year, without Khan Academy helping me get a head start before the semester starts. The high quality lectures and exercises you provide are fantastic for someone like me who may not have the ability to attend office hours and tutoring as much as a conventional student.
Thank you for all that you're doing. It's revolutionary.
