It sounds as if your question is ‘is it worth gambling $2K to see if I get into Cornell or RPI?’
But I think the bigger question is more like 'if I gamble the $2K, and get into Cornell (and we have no idea how strong a candidate you are- just that you must have some strengths to already have a scholarship in the bag), can I afford it? We don’t know whether you can afford Clarkson, and Cornell is 2+x as expensive (for you), so where does the extra $88,000 come from?
If it’s debt, imo it’s not worth it- and if your parents can write the check, the $2K difference won’t matter.
