Pepe, I would certainly suggest TKM Kollam for the following reasosns.

• In terms of placements itself it ranks above SOE CUSAT.
• Being an aided college it ranks 2nd in every aspect just after College of Engineering Trivandrum (CET).

Feel free to ask if you have any more queries.

Hope this helps!

All the best!
