The enrolment rate is contributed by 3 elements.
Firstly, the Student able to transfer which is the people who can transfer from comparable IT training/ education institution each quarter and calculated as below:
Formulation: Student able to transfer = Student_from_comparable_institution * Tranfer_rate_to_ITOA
The capacity limit is a maximum number of students who enrol in ITOA each quarter which is 2000. The profit load is decided by the capacity limit multiplied by profitable load ratio (65%). This amount will not impact directly to the enrolment rate but will play an important role later on we deal with student number and graduate rate.
Back to the Candidates, there is a percentage of acceptance rate which is 80% determine the number of students can be accepted by ITOA. Below formulation will present the enrolment rate within these 3 elements. 
Formulation: Enrolment rate = MIN(Candidates*Acceptance_ratio+Student_able_to_transfer, Capacity_limit)
The MIN function here represents the logic that if the number of accepted candidates plus the student able to transfer (*) is less than capacity limit than the enrolment rate will be that amount, however, if (*) greater than capacity limit, the (*) will be exactly the capacity limit. Because according to ITOA nature, there is a maximum 2000 students can be enrolled each quarter which is the  institute capacity limit of ITOA.
