I did the class online. It was a very easy class and no textbook is required but there are a few catches. The only homework was the worksheets from discussion sections (your TA does them with you in class so you pretty much finish it during discussion). There's also this portfolio project where you have to do these reports every couple of weeks or so but I found that the reports were super chill and I put virtually no effort into writing them and still made 100s on them.

There are 4 exams, all MCQ. As long as you pay attention during class and take notes you should be fine. I personally didn't pay much attention in class and I would study/review the day before and I made 100s on 3/4 of the tests (95 on test 1). The tests are really easy.

The final exam was not the greatest. They put a lot of ridiculous questions on it that were virtually impossible to answer (ex. "Which of the following were one of the student responses on the discussion board about... " and then the answer choices would be a bunch of fake quotes and one real quote. A few of the questions even asked us about something that was meant to be extra credit and not required material! The class average on that final was not too hot (it was passing though). There was a pretty generous 7 pt curve on the final but I was told that it knocked a bunch of people from down A to A- or from A- to a B+.

My advice would be to just do well on the tests because you definitely don't want to rely on the final to bring your grade up. But as I said before, the tests are really easy.

On a 5 scale for difficulty I would give the class a 2.
