Does the Kahn Academy follow the Textbooks?

I ended up buying the dragonfly edition. I hope I did the right thing. I ordered the teachers edtiion, study workbook A and B. The teachers annotated study workbooks A and B. And the student text. I hope I did the right thing. It was a nightmare trying to find the best deals with shipping on the books. I hope the answer keys are there so I can help my daughter figure out if the ansers are right or not. I have no experience with this subject!

Do annotated teachers editions of the Pretince Hall Biology books have the answers in the teachers key? I have not looked into the older version with the elephant.

I am really uneducated in the catagory of biology. I have been relentlessy searching for a high school biology book for my daughter to use. I have gotten down to the Prentice Hall Miller and Levine biology books. The dragonfly is a little older and less expensive and the Macaw is more expensive (Amazon) I am looking for a text with an answer key. I have searched high and low on the internet to find out what to use for the answers. I found the student text. The study workbook A and B. The teachers edition( with no explination as to what is in the teachers editions). I can't figure out how to put together the biology books with answers so I can grade the work! I saw that there is a Prentice Hall website, but don't you have to be registered somehow? Does anyone know what Kolbe Biology Answer Key is and if it relates to either of the biology books or study guides. Please! Help needed here. I think I am in over my head! Thanks, Christine
