Hello ankit,

First of all congrats for securing 13k rank in UPSEE . As per my knowledge students below 5k ranks are eligible for almost all top branches for IET till last round(it will be little tough if you are from general category) . So you have very less chance of securing good course in 2nd round of counselling while in spot round or last round counselling you may get some lower branch :)

I am assuming you a general candidate (for reserved category it will be much easier) 

All the best:)
