NMC which has replaced MCC, officially announced that NEET PG will be scrapped in favour of NEXT. But this is a process that might take atleast 3 years. Considering the fact that this was announced in 2019 and 3 years from 2019 would means 2022. NEXT probably might come into effect from the academic year 2022-23 which means NEET PG 2021 is likely to be held. Neverthless, this is just a speculation and we need to hear from any official press release.
