Dear Samul,
FMS is also known for its stellar placement record it sets every year. I am sure you will have enough opportunities in term of placements, despite of your grades.
All the Best!

you can diploma in hotel management or you can do b.sc in hotel management after completing 12th

To get into IIMs, first you need to complete your under-graduation studies. I would suggest that you choose a specialization of your liking. Also given that you have an average score in class 10th and 12th, you would need to do really well in your college. Hence is it doubly important that you pick your stream carefully based on your interest and your strengths. To get into IIMs, you will need to write CAT in your final year and get a good score so that you get interview calls.

Hi
If you hv keen interest in computers, programming, softwares etc then go for bca. B.sc in any of the core subject will lead to either msc or mba mainly. There are many pg diplomas available. With B.Sc you hv variations like electronics, astrophysics, astronomy etc for higher studies and go for research too.
Hope this helps
