IEMJEE 2018 is the entrance exam for IEM which is being conducted by the reputed IEM group for admission to B.Tech/ BCA/ BBA/ BPT/ M.Tech/ MCA/ M.Sc/ MBA courses of IEM (Institute of Engineering & Management) Group and UEM.

You may get the top IIIT but getting the IIT through JEE Main is difficult because IIT is allotted to those only who have secured a good marks in JEE Advanced .
So in my opinion you definitely get the IIIT but hope for the best so that you can get the IIT. Try for JEE Advanced so that you can get the IIT by that .
best of luck
