Thanks to the person that let me know that C.1.7 #3 was a near duplicate of another problem in that set.   Interestingly, both of these were old exam problems, again emphasizing the value of spending time working old exam problems.

I’ve removed #3, and everything else will renumber automatically in the problem system, so if you are using the problem system, you shouldn’t notice this change.  However, if you are using the pdfs, you will want to grab a copy of the new C.1.7 handouts so that your problem numbers on the pdfs will match the numbering in the solutions tab for this lesson.

In terms of updates, I’ve added 7 problems to D.1.1, and 1 to each of D.4.5, and D.6.3, as well as 3 more to E.2.2.   More to come!
