EU considers Conflict Resolution & The Essentials of Managing Conflict duplicates - so subtract the 1cr one off your list.

Also, some are probably more trouble than they're worth - anything with multiple assignments (touchstones) may not be worth doing, because they are taking a really long time to grade assignments:

English Composition I - 5 assignments
English Composition II - 7 assignments
Public Speaking - 4 assignments
Spanish I - 5 assignments

There are others with 1 or 2 assignments, which is still more than you need to do for most LL work, so you might want to consider that as you go along. But those probably won't kill you like the others might.
