[Solved] What is the "Max Strength" field used for in Student Groups?

I am just learning how to use the Education Module and trying to figure out the proper order of things. I noticed the Max Strength field in the video and it just gets filled in with a number in the video but it is not explained.

It also does not seem to appear in the manual online.

So, what is it supposed to do for us?


Max. no of students which can be added in that particular student group.
