I have qualified in emcet 2020 but my rank card was not opening 10+2 data is not available
Sreelatha, there might be a couple of reasons why you are not able to view your rank card. If you have recently had a change in your 12th board marks and have not updated them yet, you cannot see the rank card because your EAMCET rank is determined by 25% of your 12th marks and 75% of your EAMCET score. If you have applied for re-evaluation or cleared supplementary exams and have not uploaded them, you might not be able to view your rank card. Please look into that once. But if you have neither applied for re-evaluation or written supplementary exams.
I hope my answer helps. All the very best for your future endeavors!
