The exams that are given are EXTREMELY fun and enjoyable to take. The class is challenging. It's the hardest A I've ever worked for. If you're an A student that expects to get a B in chemistry, then it'll be one of the easiest B's you'll ever get. The class will turn you into a proper student if you take it seriously. The class is hard and challenging, but that's what makes it fun. Only a few people in each class get an A, so I hope you're one of them if you're planning to be serious about the class!
