A good parallel study?

I'm dropping a year now, after my 12th ie. I'm most probably appearing for the medical entrances/hotel mgt. A major mistake I made was dropping math after 10th. I didn't realise it would close all of my options in the field of computers. Anyway, leaving that behind, could you guys suggest any good course/study material to any course in Computers. More like coding/graphic development and stuff, that I can learn in close to 4 months? I have like atleast 1-2 hours per day to spend on it, other than the general studies. Any interesting course related to computers. I've got basic knowledge in Java, as I had taken computer science in 12th

P.S- I've started watching Lectures of STandFord University ( Programming Methodology)
