Query: As a college student...

I found this book difficult to understand if you don't already have a basic knowledge of Korean. A lot of the pronunciations that were spelled out phonetically are incorrect if said without some experience in the sound of Korean. I found the grammar explanations incredibly confusing and was incredibly annoyed that the directions for the exercises were not in English after the second lesson and often new vocabulary that was not listed in the beginning of the lesson was randomly thrown into the dialogue. In addition, the lessons taught have nothing to do with what would normally be spoken of during conversation. Unless you normally speak of the classes you're taking, how interesting they are, and how different the weather is during the four seasons in Korea, I'd strongly recommend seeking another book.
