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

There is no option for changing your form details after you submit it.

You can call the next helpline numbers and write to them on the email address just for mentioning sake. 

Wait fir fir their reply as there is still much tune for the exam. 

They might cancel your previous form and give you an option for new one.
