I'd be interested in knowing what type of scholarship that is. The vast majority of schools don't transfer grades from one school to the other (just whether you passed or failed). So if you got a scholarship at school X and then got straight A's at community college Y, it won't help your scholarship at school X. Of course you could have a scholarship that isn't school based...
Since you are frequenting a computer forum, I assume you have a reasonable amount of computer knowledge. If so, see if they offer any computer courses - it can't get any easier than that. Things like how to open Word, how to send email, etc are often offered by most community colleges.
However, cchen had the best idea - attend class and study. Easy A in any course if you do that.
