From the given data I can deduce that with your given and rank and the trends, both CSE and ECE are difficult to get. While looking at the CSE ranks, there is little chance that it will touch the 10000 mark. For ECE I noticed a drastic shift in rank 6303 to 10793. Maybe this year it might increase again. But nothing can be said surely as your rank is on the edge of the predicted closing rank. So getting ECE is more probable, although both are difficult to get in your case
