How to use the two-subject score weighting calculator
When a college builds a composite from two subject results, the two are rarely counted equally, and the index they read may be a percentile, a scaled score or a converted scale of the college’s own. That makes it hard to see how much the pair actually contributes. Enter both subject values, the weight given to each, the share of the composite assigned to the section and the composite maximum, and this page works the contribution out.
Each subject value is multiplied by its weight, the two are added and divided by 100 to give a weighted average, that average is divided by the index maximum, and the result is multiplied by the points available to the section — the composite maximum times the section share. If the two subject weights do not total exactly 100% the calculation stops and reports the current total, and the formula used is printed with the result.
No college formula is built in. Which index is read, how the two subjects are weighted and how many points the section carries all vary by college and by program, so there is no single rule to hard-code. If a college publishes a converted scale, enter those converted values and that college’s index maximum; this page does not build a conversion table for you.
Frequently Asked Questions
No. The index read, the split between the two subjects and the section share differ by college and program, so nothing is built in. Enter the values from the published requirements.
It does not create converted values. Enter the converted figures the college publishes as the subject values, along with that college’s index maximum, and the calculation uses them as given.
The calculation stops and tells you the current total. A result appears only when they total exactly 100%, and uneven splits such as 60% and 40% are applied as entered.
