Like I mentioned in tutorial, your textbook has a list of problems in at the end of each chapter, broken into 3 sections: Problems, Theory, and Self-Test.
While the problems have answers for you to check, the Self-Test offers suggested solutions, which can really help walk you through some questions. The theory, while useful, has no solutions given at all.
If you need to budget your time to study, focus on studying the following things: Lecture notes, Assignment questions, End of Chapter Self-Tests. The test is not meant to trick you, rather, check to see if you have a good understanding of the material. So you can expect the questions to resemble something like the “intermediate difficulty” problems — not the easiest ones, but also not the ultra difficult ones at the end.
As always, drop me an email if you need some clarification.
