Student Problem Manual for Derivatives Markets 3rd Edition

First off I thought it was the solution manual, but that's my fault not theirs, just know this is just extra problems to support the chapter material. Regardless I tried to use it and once further into the chapters, they start showing just the solution. No steps in between, and for a book made just for extra problems and solutions that seems a bit absurd and lazy. That's why I'm giving it a low rating. I would've given it a 1 star but it wasn't totally useless. Anyhow I wouldn't recommend it, but then again the solution manual (a friend of mine had) followed the same format. Have fun with Binomial pricing options, I got it but it took a little effort...

Not what I thought it was. Looking for more explanation
