His components have various credit values. The table below shows the steps required to calculate the overall score. Begin by listing the components in grade order DDDDMMPP.
Step
1 Grade D D D D M M P P P
2 Credit Value 15 15 10 10 15 15 15 15 15
4 Credit value for scoring (max = 120) 15 15 10 10 15 15 15 15 10
5 Weighting 3 3 3 3 2 2 1 1 1
6 Weighting x Credit Value 3x15 3x15 3x10 3x10 2x15 2x15 1x15 1x15 1x10
7 Add the results 45 45 30 30 30 30 15 15 10 =250
3 Cumulative credit value (max=120) 15 30 40 50 65 80 95 110 125 over max of 120
He has 125 credits and can only count 120 for scoring purposes, so eliminate 5 credits with the least value - i.e. calculate a score for 10 credits of the last pass.
Now multiply 250 by 13 and divide by 12 and round the result to the nearest whole digit = 271.
