Colleges entrance exams take place according to courses or all students in once
It depends on the schedule published by the college / university in which you are seeking admission. The college-level entrance exam can be taken in one or multiple sessions, depending on the total number of applicants for a particular course. The entrance exam for admission to different courses can be done on the same date or on a different date. Therefore, you should check the schedule to know the date of the exam. As you have not mentioned any College / University and the course in which you are seeking admission, it is difficult for us to answer your query. Please tell us the course and the name of the university so we can provide the schedule if it is published.
I hope this answer helps. All the very best for your future endeavors!
