How to enable averages?

while messing around with Gibbon I have a question. How to enable averages?, because while I was looking at settings I didn’t find it.

Hi Andrius, be sure to go into the School Admin > Markbook Settings page to Enable Column Weighting and then Enable Cumulative Marks. You will need to be using a numerical grade scale, such as the built-in percent scale, and ensure that the scale you use for averages is set as the system-wide default in System Admin > System Settings.

Hello Sandra, alright I will try it using it with 1-10 custom scale (1 worst, 10 best) if it doesnt work Ill use procent scale.

Sounds good, as long as your custom scale is set to Numerical, and set as the default in System Settings, it should work.
