hello aspirant

As you have already ranked 3900 so i think you have already gone through streams and based on that you are placed a rank. You can try for the civil engineering,mechanical engineering,aerospace engineering,electrical and electronics engineering,mechatronics. Because for the rank 3900 CSE and IT department are very hard to get at the time of counselling session but if want you can try through the payment method.

i hope this could help you

all the best
