Query: Is this book or hell!

I really liked chemistry. I thought it was fascinating. But this book completely made me loathe it. You won't understand a thing in this. It explains one thing and when you think you are getting the hang of it, it skips the whole thing and goes in a completely confusing way to a completely confusing topic. The formulas, which are considered to be really simple are given in the most complicated way, and there are times I really threw the book at the wall out of frustation. Don't ever buy this book. You will be doomed. Buy anyone's else. Nothing could be horrible than this. After reading the other reviews, I think, my review is justified.Thank you.
