UPES, Dehradun is the best college for CS.

B.Tech CSE graduates from JSS and AKGEC CTZc in campus placement is between Rs3.5 Lakhs to Rs 6 Lakh per annum. Majority of Indian Tier IT companies pay in range of Rs 3.5 Lakhs for fresh engineering graduates.

CSE in Jaypee, Noida is a better option. This college is good in terms of reputation and placements. It has a good name in engineering colleges among others. CSE have more scope than IT. So you can prefer CSE over IT.

I don't think it is a good idea to drop a year as there is no surety that next year you are going to get very good score. If you get a good score that's good if you don't then will you drop again? No, you can't keep on doing this again and again.Better would be grab what comes to you this year only and try making best of it.In case your JEE score doesn't let you take admission somewhere, try for admission in some private university where you can get admission on JEE scores/ tests conducted by them/ your marks in 12th. Some of these also offer good scholarships based on any one of the above mentioned admission criteria.

Yes they almost have the same.
