JEE Main

You can look for private self-financing colleges like Dayananda Sagar, RV, Acharya, MIT, Oxford, etc.

Sorry, the score is very low. You need to get at least 100 or above to get a seat in VJIT or Datta Meghe college.

Yes, you can expect a seat on this campus. The score of 171 is very competitive. You can definitely join the same campus.

No, you need to qualify NATA to get admission in this college for architecture.

Yes, they give admission through JEE Mains. With AIR 146, you can easily get into this campus.

Yes, since you are from OBC category, you will get a seat in this campus. This score is enormous for your admission in DYP.

The colleges which you can expect are JJ College, DY Patil, Acharya, Alliance, Dayananda Sagar, CMR, etc.

All will put the dates in their website. Kindly look into each of the college websites and apply for counselling.

Yes, you can get a seat in University of Hyderabad. This rank is enough for the admission into CS branch at HU.

With your given marks and assuming general category, you will not be able to get into CSE and any branch of IT.
I would suggest you to go for private colleges of Indore as they have good placements such as Acropolis, Medicaps, etc.
Moreover , the cutoff for HOMESTATE for CSE and general is 25 thousand to 26 thousand and for non - home state is 21k - 22k .
Best of luck.
