Hello aspirant,

Yes, there is cut off for Architecture (Entrance exams). Every entrance exam has some particular cut off. The cut off marks depends upon some factors like; Number of students appeared for the exam, Number of seats available, Difficulty of the question paper, Reservations etc....

The cut off Marks varies from exam to exam and year to year.

Yes, To join in architecture you need to cross the cut off mark.
However! it's not necessary to cross the cutoff mark, if you can buy management quota.

All the best!
