Welcome to AP Chemistry. You have reached the heights of chemistry here at Walnut High. This class is designed to meet the requirements of both the AP and IB curricula. Each student in this class is expected to take both the AP test in May. All the information presented will be helpful to deepen your understanding of the related concepts. Please continually check the calendar for updated information, due dates and homework. I am very excited about this class and I look forward to an amazing year of discovering the wonders of chemistry! Get ready for a challenging yet fun year!
