The chances are none. All State level Medical Entrance examinations and even AIIMS and JIPMER have been cancelled in favour of NEET. NEET is the entrance examination for admission to MBBS,BDS, Ayush and Veterinary courses across India. Now to conduct individual State level entrance examinations means the whole logistics and system needs to be re assigned. What we need to remember is this Pandemic will be with us for a long time. But a while Education system cannot be changed for whatsoever the reasons might be. If you look at GUJCET, it is not for MBBS. It is for BE/B.Tech, B.Pharmacy courses and so is KCET, KEAM. WBJEE, TS EAMCET, AP EAMCET, etc. So Candidates who want to pursue MBBS wouldn't even have applied for these examinations. And the exam conducting authorities and Counselling authorities are different as well. It cannot be just right or even sensible for that matter to conduct State level entrance examinations. The major loss would be for the Students because AIIMS and JIPMER will not fall under States and so Candidates wont have it easy for admission to these Institutions. AIIMS has never had a cut off lesser than 95 percentile. But merging with NEET has made admission to AIIMS and JIPMER thinkable and achievable. So there are lot many factors that need to be considered. And so just to answer your question, the chances are nil. So you have to prepare for NEET/JEE/GUJCET or whatever exams you have applied for.
