Dear Aspirant, 

Congratulations on good rank. But the chances of securing seat in JNTUK in CSE or ECE branches is highly not favorable. The previous year cut offs ate as follows :

CSE - 1127

ECE - 1136.

Hence you can look for other colleges where you can get the required branch. There are many yop colleges you are eligible for. Use the predictor tool for that.

Here is the link :

Hope this helps. 

All the best.
