Hello,

The codes which are given by NTA are very difficult to understand.

Here I simplified the codes

Code 1 - 12th students giving their boards in 2019

Code 2 - 12th passed out students 2018 without gap in between 11th and 12th class

Code 3- 12th passed out students with gap in between 11 and 12th class

Code 4- dropper students ( more than 2 drops)

Code5-  first year students of BSC with physics chemistry and biology/biotechnology

Code6- BSC passed out students

Code 7 - for NRI students

According to this simple version of the codes you can identify  which code is for you

Hope it will helps you
