How to properly sort fittings

From the best plumber Vancouver WA 98682

I have been looking for information online about how to do this and I have not been able to come up with anything.

In a few weeks, I will be taking the hands-on test to hopefully become an plumbers apprentice. Part of the hands-on test is to sort fittings which sounds simple enough but I’d prefer to not go into the test blind. Can anyone provide me with information about how to do this correctly?

Thanks in advance for any information!
