help reading book

hello, guys i am studying book "Art of Electronics" i also have student manual.
i have just stated it reading it. i am feeling hard to understand and what about the exercise, giving in the chapters? how to know that i am solving them in correct way or going wrong? mean where are their answers.?
i've just started chapter 1 3 days before.

I have no idea where the answers are, not being familiar with that book. You can check the back of the books if they have them. Otherwise, if it's circuit analysis type problems, you can input the problem into a circuit simulator and read off and compare the wanted value.

I've read it but I didn't do the excercises, was just casual reading I wasn't cramming for self testing =) I thought the book was exceptionally well put together and easy to read. I don't remember if there is an answer index in the back of the book, but that'd be where to check.
