It may be a complicated process to calculate the aggregate percentage of a degree. The reason for this is that certain assignments will have more weighting than others (they will be worth a higher percentage of the overall mark than others). To be able to calculate the aggregate percentage, you will need to find out what percentage of each year's total mark counts towards the final degree. You will also need to establish how much each assignment or examination is worth in each particular year. For example, if you studied a degree that lasted for three years and the first year mark counted for 20%, the second year for 40% and the third year for 40% then the first year marks would obviously not have as much worth as those marks in the second and third years. In fact, most universities would be able to tell you your overall percentage at the end of each year, and you should actually get results slip at the end of each academic year with your total percentage for that year included on it. If this is the case then by following the figures used earlier as an example (20% for first year mark, 40% for second year mark and 40% for third year mark) you should be able to work this out quite simply. If your first year mark was 66%, your second year mark was 63% and your third year mark was 64%, then you need to firstly multiply the 66 by 20 and divide by 100 to achieve the first year total, this is 13.2%. The second year figure would be 63 multiplied by 40, divided by 100, which is 25.2%. The third year figure would be 64 multiplied by 40, divided by 100 (25.6%). Add the three figures together to get your aggregate percentage, so 13.2+ 25.2 + 25.6 = 64%.
