Since you got an RT (Repeat Theory) in Physics and were unable to give the improvement exam due to medical reasons, you need to clear the subject to be eligible for NEET. Here's how you can approach it:

1. Check with your education board : Boards like CBSE, ISC, or state boards usually conduct supplementary or compartment exams. You should inquire with your board regarding the next available improvement exam for Physics in 2024 .
   
   
2. Apply for Compartment Exam : Most boards have a separate window for applying for compartment exams, which may be conducted mid-year (around July-August) or next year during the regular exam cycle.
   
   
3. Eligibility for NEET 2024/2025 : You can apply for NEET 2024/2025 provisionally, but you must clear Physics before counseling starts. Check with your board when the Physics exam results will be announced to ensure it aligns with the NEET counseling schedule.

It’s best to stay updated with your education board's notifications regarding the next exam date and clearance requirements.
