Is your MBA a 3 year course (2 years and 8monts) full time course or is it a 2 years full time course that you did part time over 2 years and 8months?
If it is 2 years then for sure, you will get 22 points. If it is 2 years and 8months, then I don't know because most degrees don't take complete years because the vacation starts before the year is through.
Please check your MBA points as follows.
All universities have different credit hours requirements to complete MBA.
That length of course will be assumed as period of education.
Some time your drop semester; some times you repeat the semester. It doesn’t matter how many total credit hours you spend to complete your MBA.
Only official course length will be considered.
