You have a lot of scope in PSU. Try for those jobs.

Around 60 subjects for whole course and nearly 8 subjects per semester. The subjects are prescribed by AICTE and are different for different branches. The university decides the final subjects in a course for each session.

You should be able to get Mechanical Engineering for B.Tech. But, the DTU will decide whether you are eligible for ME or not, because AICTE has given this responsibility to Institutes themselves.

BIT is usually very hard to get. Many students compete for this college, so it would be very difficult to get this college, unless you work very hard.

NMIT is the best and demanding college for computer engineering, as your rank is too high, you can go for few more rounds in counselling to get admission in this college.

The scope is very less, as your rank is too high. But, you can try for few more rounds in counselling. You may get admission in NMIT. It is one of the demanding course, so hope for the best.

You can pursue MBA or PG Diploma in Management. Both will be very good for you in terms of job opportunities, or Ph.D. will be another good option to pursue, if you want to continue in lectureship.

NMIT is better to pursue your engineering in Bangalore. It is having good academic reputation and placements with qualified lecturers. So, you can prefer ECE in that college.
