Having your category changed from SC to ST in your CUET form could potentially affect your admission process, but the exact impact depends on several factors.

Universities reserve seats for different categories like SC and ST. If your form initially reflected SC and now shows ST, it might affect your eligibility for SC category reservation benefits.

You might compete for seats in the general category or ST category, which might have higher cutoffs compared to the SC category.SC scholarships might not be applicable if your category is registered as ST.
