Title: GOOD BOOK. TEACHES A LOT
Review: The reason that I didn't give it 5 stars is cause it teaches extremely formal Korean which in most settings outside of business would sound really weird and out of place to a native speaker but the high vocabulary and the advanced grammar that it teaches is awesome! The grammar it teaches is invaluable. You will learn a lot from this book! I recommend it for beginners and even intermediate learners
