Hello,
Sorry, you are not eligible to get a seat in RGPV-Bhopal because you have low marks and as per RGPV-Bhopal selection criteria. Try different colleges in Madhya Pradesh and opt for best private college including LNCT-Bhopal, Medicaps-Indore, Oriental-Bhopal, etc., through Madhya Pradesh online counselling.

Hello,
Sorry to say but your marks are very low according to cut-offs hence you will not get best colleges in Indore as well as Pune. But you can try for state-level counselling so that you will get some medium level colleges in Indore as well as in Pune.
All the best.

Hello,
Hope you are doing well. If you want to get a college in Pune then apply for MHCET and give the examination based on this marks you will have a chance to get colleges in your selected branch. Else you can go for state level councelling which will be happen in Maharashtra. Try to get admission through this.
