Hi Rishikesh,
KJ Somaiya is an autonomous college, hence it provides state level seats irrespective of your university. The last year cutoff for Mechanical engineering at K J Somaiya was 147 marks.
I would suggest you go through the last year cutoffs of all the rounds of CAP Process on the following link.

Already first round is over. Now you can have a look at current vacant seats if any for your desired college and hence know the chances of getting it.

Best of Luck!
