How to Calculate your QCA: The Formula:
Semester QCA = ∑ QCS Cumulative QCA = ∑ Semesters QCS
∑ (AH-NQH) ∑ (Semester AH - Semester NQH)
Att Hrs: This term literally stands for 'attempted hours' but does not actually represent the number of hours you spent attending modules - the term has been carried over from a previous time when QCA was based on numbers of hours per module. These days, Att Hrs represents the sum of the credits of all modules attempted by you in a given semester. For example, in the tables below show the calculation of autumn and spring QCS, the sum of the module credits is 15 in both cases.
Cred Hours: Credits assigned to each module. Again, this term does not literally represent a number of hours. It represents the sum of the credits of 'quality' or 'credited' modules, i.e. modules that affect QCA.
Non-Q hours: This stands for the sum of the credits of modules multiplied by the factor where you received the following grades: I, P, G, M, N, Ex, R and W, i.e. grades that do not affect QCA. For example, co-operative education placement, which is graded on a pass/fail basis (P for pass or N for fail) does not affect QCA.
