Hi,

Here are some tips for you :-

• Maths is compulsory so give improvement for future needs.
• IIM A, B will be difficult to get unless you perform extraordinary well and get a 100 percentile or so. Others might accept, In any case, some oldies and most new ones will be open for you.
• There are other very good colleges as well, Don't think much, If you want to go for MBA Go for it from any good college.
• IIM A,B doesn't guarantee ones success, Its ultimately your hard work.

Hope this helps.

Good luck.
