Introductory psychology is a joke like someone mentioned above. You'll will jump from topic to topic, learning about different theories that have been debunked in one way or the other, but that still doesn't stop professors from telling you about the theories. Then all the sensationalism about psychology, etc.. We spent a few weeks learning about Freud's theories that have been denounced, but other than that, expect a broad overview of topics from learning about the brain (which was pretty good) to learning about perception (although we spent a week on this subject, it was by far the best topic out of the whole class).
Read, mostly understand the reading, etc..., and you'll do fine. I didn't necessarily take notes in the class or from the text (I didn't buy it), instead I used wikipedia as a reference to the class lectures to reinforce what I learned in the lecture. Passed the class with an A because the professor mostly conducted his tests on level of comprehension more-so than memorization of facts and dates, although they were a part of the test very sparsely.
Most people in his class were on the low range of the B scale to C's, primarily because they memorized certain data points and weren't fully integrating their minds into the source material. When you are given examples of hypothetical cases and are asked to give an answer to a series of probable answers, you better hope you understood the material well enough.
Like everything though, you will know once the first test hits your desk on what to expect.
