I’ll second that I think your stats and ECs are unlikely to get you into Stanford, MIT, and CMU. If you can maintain your GPA and get you SAT up 100 points or more, you’d be a good candidate for merit aid at RIT. I think you’re a good candidate for WPI and RPI but you won’t stand out as much and therefore may not get much merit aid.
Is your max $40k-$50k per year or for all four years combined?
