I have decided to post this instead of the usual, "nice question" comments...
This might not be correctly on topic but I have noticed something (and most likely this is not a unique phenomenon) - I am not truly interested if I got the "answer" right. I am more interested in if my thought process was running down the "correct" path.
I have been keeping some notes (excuse me while I hype OneNote for a second) on all the QotD's I answer along with the "thought" process behind my answer (I also note if I totally mess up and where I went wrong). In looking through the notes, I have found, the more QotD's I answer, the better my thought process has been.
Interesting note: still screwing up on the correct answer portion. The minute details of an exactly process/procedure/feature still escape me. I still get hit by the little gotcha's. I figure once I have a "proven" track record for understanding/thought process, I will start working on remembering the details.
