Overall, limits aren't a problem for me at the moment. For the homework in section 2.3, though, I'm ehhhh on two problems.
The rate of change section is icky. I get it, but I feel like plugging in all the numbers gets tedious / annoying after a few problems. And Mr. Flint, I agree.. it's annoying that the book problems go back and forth between calculator and non-calculator. And on another note, I personally like the lessons and practice problems from the Larson site better than the lessons and problems from our actual calc book. :P
