Hi Shubham,

Based on your marks above,

You have 2 clear choices in front of you at the moment 

1) Join a tier 3/4 private college.

2) Take Drop year and try for IITs/NITs next year.

I would highly recommend taking the second option , for a clear reason that getting a good college tag always stands out on your resume.

Plus the facilities and freedom you get at top colleges are amazing and unmatched (trust me i am in IIT myself).

and dropers do have a very good chance at clearing JEE M/A provided you study consistently and hard for 1 year.

(11 out of 20 of my wingmates here at IIT-K are droppers and some were in situation just like yours).

All the best.
