Are Morin's Problems and Solutions in Introductory Mechanics meant to be difficult?

Homework Statement:: n/a

I have been going through the baby version of the Morin Intro to Classical Mech book, "Problems and solutions in introductory mechanics." Each question, even some/quite a lot of multiple choice, is making me think upwards of 5 minutes and reconsider whether I know what I think I know. Was wondering whether this book is meant to actually be difficult, and whether there is any way for me to solve these introductory mechanics questions faster, or if I am going fine.

Morin states on his website that these questions are like one/two star questions in his 2008 Intro to Classical Mech red book.

If you post a couple with your solutions others may be able to help you find quicker ways.
