Yes, according to the normal process, the Joint Seat Allocation Authority (or JoSAA) required a student to score at least 75% in class XII boards or be in the top 20 percentile of the respective boards, but for the session of 2022-23 through JEE Main 2022, JoSAA has notified that the 75% criteria has removed due to COVID-19. So, yes, the 75% criteria has effectively been removed for IIIT Allahabad. All the best!
