This is quite likely, especially for the beginning (which is mostly on computation, my area of expertise). That said, I’d guess that your difficulties stemmed from not knowing a good way to approach the problems, and being intimidated by terminology. I bet that if you work your way through a few of them with a friend, and get a feel for how these types of question are tackled, then the other exercises will seem much easier in short order.
I’m also more than happy to go over the early exercises in the book with you, if you want some assistance. PM me if you’re interested.
