Friday is review day, so we went over both the A and B lessons for the week.  I missed the Fundamentals class on Wednesday, so I'm still a little sketchy on the double underhook pass - especially the middle step when you sprawl and set up the second underhook.  Hopefully, I can work on it a little bit next weekend before the new lesson take hold.  
One thing Rodrigo and Lance pointed out is that I've got a habit of keeping my elbow wide when I change levels during underhook passes.  It's an easy enough thing to fix.  But the problem is that I don't do underhook passes often enough to make the new, good habit stick.  My guard passing game is very much smash-the-leg oriented.
So maybe this is an opportunity to fix that.
