I am for classes about touch typing. The problem is that, as dr/owned said, there's not necessarily an incentive to pay attention. Unless you're covering the labels with a silicone keyboard cover (or, perhaps you order Otaku boards - kinda doubt it for a computer lab), you won't gain from it. I was religious about not cheating when I took typing (which was harder, as I could have easily). I was one of a couple people who actually did so.
In the end, I made some money on the side. People would pay me to retype their paper with corrections and I'd have it done in 5 minutes (I wouldn't write any of the content; I would merely make any corrections they/their teachers had indicated.
I don't type fully proper though. Type to Learn did not give me that. I tend to type pretty freeform. I use the nubs to get back to F and J, and I use my pinkies on the modifiers, and I use the space bar with my thumbs (heavy preference towards the right thumb), but I don't always return every finger to the home row.
