Dear Ubaid, GGS IPU MBBS registration form has no correction window which means you may have to fill in a new application form and that means another payment. So we would suggest you to wait until 2nd week of June tentatively because that is when NEET results will be announced. Because, GGS IPU hasn't mentioned any last date for filling the application forms yet, you still have time. Once the results have been declared, IPU will release its cut off marks for various categories. If you meet their qualification cut off, you can fill in new application form. That way you would be saving money.
