Bangalore

College of Engineering Pune is famous for its CSE branch.
So, it would be the best choice amongst the three.

Hi Bibin,
With no doubt in mind, you should go for UTM Shillong.
UTM offers CSE with specialization of Oil and Gas informatics and Cloud Computing that too in collaboration with IBM.
To know more about their B.Tech admissions and procedure you can take a detailed go through at their website- http://www.utm.ac.in/

Hello Nayeem,
You have posted a very interesting query. I feel there should be some institution to teach drop outs. Presently, you will have to take tuition and pass the subjects in which you have failed.

Companies from all specialisations came to our campus for selection. Marketing, HR, and finance were the ones most sought-after. There were companies like IBM, ICICI, Deloitte, E&Y, Indiabulls, Birla, etc. queuing up to screen students. I got selected to a renowned finance company with a package of 5.5 LPA. The placements are really great and a lot of companies come on campus interviews. Great opportunities are being offered to students who can make a career immediately after the course being completed.

IIBS is rated India's No.1 emerging B-School in Bangalore With 100% placement assistance., IIBS offers full-time MBA for a period of 2 years and is approved by AICTE. The course has been recognised and approved by UGC and Ministry of HRD. Ranked as the top 3rd B-School in All India, its placements are really great and a lot of companies come on campus interviews. Great opportunities are being offered to students who can make a career immediately after the course being completed.

Symbiosis, Pune is better as compared to Christ.
