At present if your studying in intermediate.

You should pass the all the subjects in the intermediate board.Else ,you will not get the rank in the EAMCET ,even though you passed in that examination.

EAMCET is the examination you need to apply and get the marks above the cut off of that respective year.

After that you need to get attend the counselling choose the college and arrange them according to priority .

And that's how you will get an admission to an engineering college.

If you want to get an seat in JNTU HYD , you need to get the rank below 8000( atleast*).

i would not suggest you to join JNUT try for nits

Good Luck
