If this is about NEET, your code shall be 01. Because for NEET, Chemistry is an important subject that needs to be passed. So, it will code 01. Code 01 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.

Unless you clear Chemistry, your admission will be provisional and hence your code will be 01.
