The neet 2021 application forms has not been released yet. But we can expect that the officials can release the registration forma of neet 2021 in the last of january or the first week of February. And the exam will probably be taken in month of may ( first week ).
Also keep regularly checking the neet offical site for more details.
The syllabus of NEET 2021 will be from Physics, Chemistry, Biology of 11th and class 12th science CBSE syllabus. Also as CBSE has 30% reduced the syllabus for CBSE class 11th and class 12th so, the neet syllabus will be cut accordingly and the same reduced syllabus will be asked in neet as pee the latest news declared by education minister. But as the official brochure has not come, so you can expect the same previous syllabus of neet.

if i were fail in NEET & EAMCET Exams and i got 50% in intermediate , I was in a serious situation to know the answer?? Every one are suggesting me to so the job !, you are not eligible for study!, they saying!!
Don't hear to those who are so demotivating for you. You are always full of probabilities. If you can't crack NEET/EAMCET this time try to do next or try to do anything else if you are interested in it.
Failing an exam doesn't mean that you are a failure. So don't bother with such people. You should follow up and prove yourself.
I hope my answer helps. All the very best for your future endeavors!

As you have asked for Karnataka so likewise in Karnataka also there is no reservation quota for NCC certificate holders.
