Nailed it! ...or not

I decided to try some CW practice tonight. Using LCWO.net I reviewed lesson 1 which teaches K and M. I had learned this a few months ago and still remembered it pretty well. When I moved to lesson 2 I had a really tough time distinguishing K and U.

I decided to work on just K and U together using the custom feature on LCWO. I went through it once and got about 85% accuracy. The second time through I finished copying my code and felt like it was 100%. "Nailed it!" I thought to myself.

Well, as you can see below, I did get 100%...100% wrong!  I have somehow reversed K and U in my head and am now struggling to reverse it back!

CW is hard but someday I am going to master it. Probably not today though.
