Hello prerna,

It is little disappointing but to be honest, you cannot get into top colleges with these marks. IHMs like Delhi, Mumbai, Bangalore,Kolkata, Lucknow etc are out of reach. The only colleges that you can get are 

• IHM hajipur
• IHM Srinagar
• IHM Meerut

Little chances of getting IHM Guwahati .

Don't lose hope still you have lot of options available for you. Keep trying till you land into some good college.

Ask if you have any further query in comment .
