Hi...

Sorry to dissapoint you but previous exam has no connection with the current exam.So don't care about last year and concentrate on your current exam.

yes every year the cental government will comnduct the JEEmains there will be seperately declared results and no two year results will be combined so there is no use of the last year score and again you have to perform now in this year exam of JEE as there will be some seats only available only in that particular year and that seats cant be forwoded to the next year so that no student gets a loss , so when you got a score card in the previous year you have to join in that year or there will be some universities which provide seat according to that year score card and you can use that year score card in the same year and you cant use that score card for the next year so hope that you will definetly get passed out in this year too and you can join in a good nNIT or IIT too , hope that you get succeded and all the best for your future

hello omkar, jee mains score are valid for one year only so i dot think so its of any use in 2019.

I hope this helps. all the best.
