I am not able to proceed through the AIIMS final registration process even after the code generation, it still shows provisionally accepted.

Dear Kavitha, there have been issues with the registration process and the payments. Students who have faced the same issue cleared the cache, browsing history, restarted their system and relogged in. It worked for few immediately and it worked eventually for others. It might take time but you will be able to.

Once you generate the code, go to the Application form and fill in the Qualification details. In this column, you will be asked questions like preference of language for the exam, if you are a repeater, Qualifying exam details. Verify the details before you click 'Next' because you cannot edit anything once you make the payment. Once you click on 'Next' you will be taken to the Payment page. Before making the Payment you can select the availability of a Seat by clicking on 'Check City Choice'. However you can select the city only after the payment has been done. Take a print out of the final page as a confirmation.
