How this was calculated
  1. 1Multiply each average by its credits3.2ร—60 + 3.6ร—15 = 246
  2. 2Divide by the total creditsรท 75 = 3.28

Formula

Cumulative = (previous ร— previous credits + new ร— new credits) รท total credits

This is a weighted average where each average counts in proportion to the credits it was earned over. A period with many credits therefore weighs more heavily than one with few.

Worked examples

Previous 3.2 over 60 credits, new 3.6 over 15 credits

Common mistakes

  • Simply averaging the two figures without accounting for the credits behind each one.
