Fix the letters
Each kind of thing needs its own letter, so we can tell them apart when
we write them down. Change one of the two letters, then press OK.
Learning for Mastery
If anything is too much of a challenge, let us know, because that just
means we found something we need to work with you on.
The purpose of any test is to find out what you need to learn next. There are no grades here, just guidance for what might be good to study next.
