Hi Sachin ! To predict your rank you may use the "career360 " rank predictor as well as college predictor app. Still I can give you a tough idea by analysing the previous year trend. Your 68 marks may fetch a rank of 5500-7000 depending on the difficulty level of the question paper. But if you follow the normal the normal trend then your may not cross 6500 also. But if the difficulty level is not so high then rank may extend upto 10,000. So all the best.

And feel free to access if any queries are there.
