Wrong answers to problems in "Introduction to Electric Circuits, 8th Ed"

AbbeAbyss

I'm studying electric circuit analysis on my own using "Introduction to Electric Circuits, 8th Ed, International Student Version" by Dorf and Svoboda (ISBN 978-0-470-55302-2 to avoid any confusion) and it seems like every other problem I try to solve has an incorrect answer in the book.

If anyone has used this book for studying, did you experience this too or is it just that I happen to have the misfortune to choose the problems with incorrect answers for the most part? (or, do I simply suck at circuits!? LOL)
