Daga, your code will be 01. Code 001 says: A candidate who is appearing in the qualifying examination, i.e., 12th Standard in 2020, whose result is awaited, may apply and appear in the test but he/she shall not be eligible for admission to the Undergraduate Medical Courses, if he/she does not pass the qualifying examination with the required pass percentage at the time of first round of Counselling.

Though you have passed in all subjects, as you are yet to pass in Mathematics, you will be not considered as 12th pass and you will be appearing for 12th exam in 2020 and so your code will be 01. Having said that until you pass in Mathematics and secure a minimum aggregate of 50% in Physics, Chemistry and Biology, your admission to a Medical College will be provisional. It means that even if you qualify in NEET and secure a good rank, your admission will be only possible if you pass in Mathematics and secure the minimum aggregate in Physics, Chemistry and Biology. It is 50% for General Category, 45% for PWD and 40% for Physics, Chemistry and Biology.
