for IIT colleges u have to clear the cutt off. but clearing cutt off doesn't gurantee Your admission. Your rank should be under 8000 for IIT colleges. and if u want good one with good branches. then u have to work hard and Your rank sjould be in 2000-3000.
best of luck

There is a big differnce between NIT AND IIT. its like comparing rolls royce with mercedes. although both are govt colleges. its not that all IIT are good. even nit' are also good. even nit patna is much better than IIT patna. so there is a differnce but it will nit effect Your quality of education. they both are equally best colleges.

You are adviced to appear for JEE Mains examination and if you make it in cutoff list you will be required to appear for JEE Advance to seek admission in IIT. Syllabus for JEE I based on CBSE +2 stage syllabus. Following are JEE preparation options: Self Preparation, Correspondence or contact classes by JEE training institutes. You may chose based on your own strength and weaknesses analysis and your personal conditions.

If you have not got job in campus placement after completing your B.Tech CSE you will face challenges in getting appropriate job directly. Therefore, M.Tech in CSE in IITs is an excellent option. MS abroad is an expensive option, therefore, you may do ROI analysis before taking a decision.

Why private college.?
