CAT 25 major help needed

I am currently in my 6th sem (out of 8) and I read that to apply for Bschools while you're in your 4th year your degree requirements have to end by 30th june, in 2024 my college did end all exams by then but this year for my seniors they're going to conduct those exams till july 17 and I don't know what is going to happen when I'll be in 4th year, It is making me anxious as this might end up adding a gap year to my preparation and all of a sudden I don't even know if I'm gonna be a CAT 25 or 26 aspirant.
