How to Calculate your QCA: The Formula:
Semester QCA = ∑ QCS Cumulative QCA = ∑ Semesters QCS
∑ (AHNQH) ∑ (Semester AH  Semester NQH)

PLEASE NOTE:
Quality Point Value
Grades A1 to NG are each given a numerical value known as a quality point value (QPV) on a scale from 4 to 0. These values are then used to calculate your QCA. Grades G, I, M, P and N have a QPV of zero and do not affect QCA. Grades F and NG do affect QCA. The following table shows the QPVs associated with each academic grade
Grade QPV Grade QPV
A1 4.0 F 0.00
A2 3.6 NG 0.00
B1 3.2
B2 3.0
B3 2.8
C1 2.6
C2 2.4
C3 2.0
D1 1.6
D2 1.2
Factor: This is a weighting that's given to each year of the programme. Programmes that include a threeyear part 2, year 2 carries a factor weighting of 1 while years 3 and 4 each carry a factor of 2. 
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.
NonQ 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, cooperative education placement, which is graded on a pass/fail basis (P for pass or N for fail) does not affect QCA.

QCS (Quality Credit Score) = (QPV*Credit*Factor)
For the purpose of calculating QCA scores, most modules are given a weighting, which is referred to as a
credit on your transcript. Modules are predominately allocated a credit of 3, or a multiple of 3. Your QPV score for a particular module is multiplied by the module credit value (e.g. 3) and multiplied by the factor to give what's known as your quality credit score (QCS) for that module. Your QCA for each semester is calculated on the basis of the sum of all your QCSs within that semester. Your overall QCA at any given time (your cumulative QCA) is based on your total QCSs to date (excluding part 1 scores where applicable).
Eg QCS for module FR4141(table 6.1) B1 = 3.2(table 6.0) * 3(credits (table 6.1))* 1(factor (table 6.1)=9.6
The following tables illustrate how QCSs are derived by multiplying the QPV for each module in one semester e.g. autumn) by the module credit and multiplied by the factor. (All modules in this example are given a credit of 3). The overall QCS is the sum of the individual QCSs.

Autumn Semester QCA = ∑ QCS____________
∑ (Att Hrs  Non Q Hours)
We will now work out semester QCA from table 6.1. Beginning with the autumn semester, QCS is 43.2 (sum of module QCSs), Att Hrs is 15 (sum of module credits multiplied by the factor), and there are no NonQ hours. Applying the QCA semester formula gives us:
Semester 1 QCA = 43.2 = 2.88
15
We will apply the formula to the sample spring semester figures from table 6.2. This time, QCS is 40.8, Att Hrs is 15 and NonQ hours is 0. Therefore:
Semester 2 QCA = 40.8 = 2.72
15
Calculating Cumulative QCA
If you look to the extreme right of the 6.1 table, you will see the last figure of both columns under the Session ToDate column heading is 2.88. The 2.88 on the left represents QCA for the autumn semester of year 1, and the 2.88 on the right represents QCA to date. The figures are equal in this case because this is the first semester of the programme.
As you progress through your programme, the second column in the Session ToDate column gives cumulative figures for Att Hrs, Cred Hours, NonQ hours, QCS and QCA. In the case of a part 1/part 2 programme, QCA starts afresh at the commencement of part 2 so cumulative figures are exclusive of year 1 scores.
Cumulative QCA = ∑ Cumulative QCS 84
∑ (Cumulative Att Hrs  Cumulative NonQ hours) 30 = 2.80
Please note that in 2009/0 the University of Limerick has moved to ECTS credits (European Credit Transfer System). For further information on ECTS please refer to our website for details on students in this transition period. Students who have started their programme in UL Credits may have the factor adjusted to neutralise the move to ECTS  for more information refer to: /web/WWW/Services/Student_Affairs/Student_Administration/Student_Academic_Administration/
