Hello Rama, 

First of all congratulation for performing well in your exams. With a rank of 9277 in TS EMCET 2019 you can definitely get a seat in OSMANIA UNIVERSITY with mechanical engineering and there are 20% chance of you to get MECHANICAL in JNTUH. Talking about CSE, there is very very very less chance to get CSE in OSMANIA UNIVERSITY and no chance in JNTUH.

So go for mechanical, and if possible then take CSE. 

I hope you will find my answer helpful 

All the best.
