Class average for each assessment

Hi, just got the app, also not too expreienced with spreadsheets. I want to do what the person above is asking but cant seem to do it. I have also read the intructions and cant find what I need.

I want the average score to appear at the bottom of each column - so after the last students score the next box will be the class average.

Any help would be appreciated, I have been looking but cant find how to do this

Welcome matt36415,
Here it is. Tap and hold on the last cell and you will be able to choose which calculation to show.
