Hello Rishabh, 

When compared the college in kerela then CUSAT always comes under top 5 and one more thing its not a college, it's a university. Now considering the national level colleges then the ranks are being taken by IIT'S, NIT'S, BITS, VIT, IIIT'S etc. Now coming to the best branch you must take in CUSAT.

• Marine engineering 
• Safely and fire
• CSE

The placements are good for first 2 branches and 80% for the CSE. The placements are very bad for mechanical and electrical. So i would suggest you to try for CSE or look for other colleges. 

I hope you will find my answer helpful. 

All the best.
