These are what would be the lectures in a live class . I have written some of them, but I've also used essays written by others.

We still rely quite heavily on the course text book. Read each chapter and be able to answer the reading questions.

Together, these sources provide a common core of geographical study for the class, but you should not regard these as being either complete or comprehensive. Expect to supplement them with secondary sources of your own. An old college textbook would be good. If you can't find one at a used bookstore, any college library will have some in their stacks that you can check out.
