- Description

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 IB student in this class is expected to take both the AP and IB tests in May. All other students are expected to take to AP test. Since this is a hybrid class, there may be information that is not applicable to both tests. Regardless, 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!
AP Test: Monday, May 2nd, 2016 AM
IB Test: Thursday, May 12th, 2016 AM for Papers 1 and 2
Friday, May 13th, 2016 AM for Paper 3
