General ⇒ How to get the maximum value of a counter

[nv22nv]

Hello,

Currently, I create assignments for my pupils using Latex. Excercises are numbered using a counter, yielding something like

• Exercise 1
• Exercise 2
• Exercise 3

I created a counter that automatically inserts the number of the excercise when I use a custom command "\exercise".

What I want to do now is add the total number of exercises to the text, e.g.

• Exercise 1 of 3
• Exercise 2 of 3
• Exercise 3 of 3

It would be okay for me if I had to run Latex twice to get the results desired. I thought that it might be possible that Latex can save the maximum value of the exercise counter and use it when it's run again, but I don't know how to do it.

Can someone please give me a hint how I can achieve what I want?

Thanks in advance.

Edit: Spelling.
