You have not got the right concept. That time there were less seats so things were a lot different. Besides, at higher marks there are fewer people per mark whereas the number really goes up in the lower marks.

I estimate a cut off greater than 205 for sure and ther is a good chance of a cutoff being 225+-5-10. However don't be shocked to not get qualified in case the cutoff stays upwards of 230 which is again a possibility.
