Hi Mukundhan,
Under COMEDK there are many good colleges that have good infrastructure as well as placement department.If you get a good rank probably within 5000 or even 10000, then you may get yourself enrolled among top ranked colleges having good placement records for CSE.
At the same time if your are able to take admission in Manipal, Udupi, then no doubt you should opt that. Then the only thing you should be looking forward in order to select between COMEDK colleges & Manipal is how much you want to spent pursuing engineering.

1. RV College
2. MS Ramaiah
3. JSS
4. SJCE,Mysore
5.BMSCE

7. DSI
8.PES

I would suggest you to make your career in unconventional field as they are less saturated and have better job opportunities. Like You can go for a degree course in Travel & Tourism. Many universities offer BBA in Hospitality, Travel & Tourism, under this you will acquire a thorough knowledge and understanding of Marketing, Sales, Tour Planning, Tour Operation, Holiday Consulting and foreign exchange management for tourists. I would advise you to look for UTM, Shillong a university which is famous for its BBA Hospitality, Travel & Tourism program. Being a tourist destination(Shillong) itself, Students in UTM gets ample of experience in this industry and gets to know and in and outs too.
