Hello

You can write exam this year but it will be your final chance for JEE mains.

And the way of exam has been changed ; now it is conducted online and you are given 2 chance in a year ist in january and other in April ( out of which highest percentile score will be considered for final ranking).

So you can give the April exam and it's registration starts from February .

Pattern is same but it is conducted in many slots so the percentile system is adopted.

But you can not give jee advanced .

Any other doubt let me know.

So good luck

Dear aspirant.

You can appear for jee main 2019 as you are qualified plus two in 2017 April session as January session is already taken place.The April session applications are expected to be accepted in the first week of January.
