Hello Aspirant,

As you have passed your class 12th with such decent percentage so you have good chances to get some colleges for B.Tech in CSE because there are some engineering colleges that offer B.tech seats on the basis of class 12th percentage and even some state like Rajasthan, Tamil Nadu where counselling is done on the basis of class 12th percentage. So even if you have not appeared for any of the entrance exam for B.Tech then also you can get admission in B.Tech. but the condition is that if colleges would accept admissions these days because in most of the colleges new session has been started and seat allotment has been completed or about to complete.

Since you have not tagged or mentioned any college for which you are concerned in the question so it's quite difficult to guide you with an accurate information.

I hope this information helps you.

Good Luck!!
