I hope this thread is still on your radar Avanish11. Honestly, when I was in 7th grade I was much more interested in beating the crap out of Mike Tyson on the Nintendo...but to each his own. There's a lot of good advise in here already and its pretty clear that you'll need to first focus on High School. I'm going to assume that you're a decent math student. If not then you've got a little under 2 years to figure it out. Get a tutor if necessary but get those fundamentals down and eventually you'll be doing Game theory
in your head. Hey, if you do well enough in High School you might get a scholarship. But don't count on it. Work and save but heed Jipstyle's warning. Grad School is mutually exclusive to a full time job unless you don't plan to sleep. Either way it sucks.
The high school district in my area has a program that allows 16 year old students to take courses at the community college for High School credit. In 2 years when you get into High School keep it in mind. If by then you're still interested then please, please ask your guidance counselor if there's a similar program at your school because it will be your foot in the door and its the best, and underused program a public school could ever hope to have. College courses are worth double and sometimes triple high school units.
My sister in law went to Penn State
. They have some pretty cool research going in the Computer Science & Engineering school. They're probably responsible for part of SkyNet. I "officially" began Grad school at the University of Illinois
but soon ran out of time & money. At the time were in the top 10 Computer Science universities.
In the real world, people with work experience and a college degree (any degree) are worth more than those with certificates. Nothing against the folks with the certs, but the programs are costly and often too specific [Example: MCSE or CCNA] to be applied to the very diversified industry.
