Greetings!

At 75 percentile even with SC home state quota, admission in YMCA doesn't seems to be possible. As to make into any meaningful branch one must score minimum around 85-90 percentile, however you can get some branches like "Environmental Engineering" or something of that sort. However on an personal level I don't recommend these branches to people unless they have genuine interest in it.

To check which other colleges you can get you can use following predictor
