Hello

According to the Rajasthan NEET UG Counselling 2024 guidelines:

- Registration and security deposit payment can only be done during Round 1 of counselling.

- Candidates who miss Round 1 registration cannot register directly in Round 3.

- However, candidates who registered in Round 1 but didn't get a seat or didn't join the allotted seat can participate in Round 3 without re-registering.

To confirm, please check the official Rajasthan NEET UG Counselling 2024 website or contact the counselling authorities directly for the latest information. They can provide clarification on your specific situation.
