I purchased and have been studying the Kaplan book and have become quite disouraged. Who was the one who was supposed to edit this book? I have several areas where the questions asked and the available answers do not match the answers said to be correct in the answer key. For example, a question asking the correct spelling of a word was already correct so I chose that as my answer to the question. When I turned to the answer key, the word in the question should have been misspelled. This type of thing did not only happened in the grammar section, but also in Math and Social Studies. Now I wonder if I have spent the whole summer studying for a test that I will fail because the book I used to study from was poorly written. I am also wondering if the material that I don't know is correct or if there are other mistakes.
