For designing you can go for B.Des in automobile design and in Pune you can go for DYPDC.

Congratulations.
So, coming back to your question, I would like to advice you to take one more chance and try to score more in the competitive exams which tier 1 b school considers. But if you don't want to try then I would suggest you to keep it on hold and try to crack other famous b schools like

Christ University is best amongst three you have mentioned for its placements and brand reputation. BIMM is decent enough and can fetch average jobs and salary.

No, it will be very difficult to get a good college with your score. I suggest you give other management exams such as CMAT, ATMA and MHT-CET.

You should try once again and give other management exams as well because your score is low. Give CMAT and ATMA in January and February respectively.
