You're probably right. But not necessarily.
I went to school in MA and the last non- sterile compounding we did in school was P2. By the time I graduated, I hadn't compounded anything but a few IV's in over 3 years. It's possible he's just super-rusty.
If you compare that to the curriculum of any school in NY state, you'll see why the out of state pass rate on the wet lab is so much lower than in-state.
