According to josaa will I get engineering branch which I have opted in first round of josaa after the second round
No you have choosen the slide option means if you upgraded the branch in nit Warangal ( same college ) than you will get newly alloted seat / branch.
If you are not able to upgrade ( by any circumstances like your rank and no vacant seats etc ) than the same branch will be alloted ( mettalergicul ).
Good luck.
Could you please rephrase your question.
Thankyou
