Explanation of Fees

Admissions Exams

Prospective students take four admissions exams: a MAP test for academics, a TOEFL test for language, a writing test, and a personal interview. Admissions Exam fees cover the cost of the TOEFL and MAPS tests as well as overtime for employees. The school does not i ssue refunds for exams.

Summer School

MUIDS maintains a rigorous curriculum designed to prepare students for the university of their choice. Some applicants need additional preparation before entering MUIDS and are accepted with the condition that they complete a summer school course prior to the start of the academic year.

Security Deposit

A security deposit is required to maintain the condition of MUIDS’ campus and property. The full amount is returned to parents after their child graduates unless a student damages the school’s facilities or equipment. The administration will deduct the cost of damages from the security deposit and return the remaining amount.

Textbook Deposit

MUIDS loans students the textbooks they need for their classes. Parents are required to pay a deposit for them when students enter MUIDS. They will receive a full refund if all textbooks are returned undamaged. If a student damages a textbook, MUIDS will deduct the cost and return the remaining amount.

Accident Insurance

Students are required to take one, week long field trip per year and can take several others. In the case of an accident, their parents are contacted while they receive appropriate medical attention. MUIDS uses this fee to ensure students’ can receive the medical care they need when they need it most.

TOEFL/MAPS Tests

The school uses the TOEFL and MAPS tests to periodically assess students’ language growth and academic achievement. These tests are necessary to ensure that students graduate with the academic skills and English language level they need to enter the university of their choice. They take a MAP and TOEFL test twice a year.
