Sorry for the late reply.

Yes, 220 is sufficient to get admission in a good college. You should wait for the counselling.

Don't expect high salary package from this branch. SPA-Delhi is one of the finest institutes for B.Arch.

You need to score a minimum of 140 marks.

Yes, you can get admission through MHT-CET in Maharashtra state colleges.

Do you really believe that you have a chance with just 33% marks? With these marks I am afraid you have less chances to get admission in any government college.

First, I would like you to be more positive. Why expect less than 50%? JEE Mains can give you admission in NITs or CFTIs and it is basically for IITs. Ranking depends to a great extent on your performance in the exam and to a limited extent on the scores of other students. Better the rank, better the institute you will get.
