Hello Manjunath M Konnur 

Though 37K in KCET is quite less score. but as per your question, hope is there.

there are many colleges that takes till 45K also. 

so you might get a college but getting a good or decent college is quite tough.

I would suggest you to drop a year or find an alternative to get into other colleges or try comedk or any other exam, as getting with 37K rank will not land you onto any goos college.

Hope that helps!

All the best!
