### What Do I Need To Learn?

The objectives for each chapter are given in some detail in your textbook at the end of the chapter. You will be responsible for being able to work the types of problems done in class and recitation, suggested end-of-chapter problems, and problems on the LON-CAPA homework set.

In addition, from time to time, there will be certain things you will just have to memorize, as you would a vocabulary in a language course. Below I list these specific things you will need to learn from memory.
