Hello dear,

Getting low marks is quite natural. But you have to learn to work hard. I can assure you that you are still having a lot of options available for you. There are colleges like MIT Pune, Francis Dy Patil in which admission can be taken at some low marks also. Otherwise management quota option is there. Try to go by your rank of possible.
