Lishan has a great understanding of Units 1-4 of AP Chemistry. As a an AP Chem student, I can say that Lishan teaches like my chem teacher, which is a great thing. Especially, the free response questions are important on the ap tests and exams because they really test your knowledge. Nice job with you thorough explanations of these free response questions from Units 1-4!!
