If you don't know what a mean or standard variation is... ask your maths teacher!

Notes:
-
The new ITA course seems to have either a harder exam or a weaker cohort compared to IPM.
-
You can see that IPM/ITA is consistently marked down more than IS/SD across the range of marks (except, obviously, for a score of 50 which never gets marked down).

Again, the new SD course's mean is down compared to the old days. The range of marks (stdev) is also down.
