# Performance Expectations Calculus 2

The Mathematics Department has a standard of performance expected of calculus students. The following pages describe in detail what you need to be able to do and what you need to understand to receive an A in Calculus 2. This provides an excellent checklist you can use each day to make sure you have learned the material well enough. Before an exam you can use the list of expectations as a checklist to make sure you have reviewed everything.
