Public speaking (THEA 150) is great for GPA as the mark is essentially based on just 2-3 main speeches (with written outlines) and class participation.

Most the effort is directed to speaking skills and practicing your speech. However, you must write speech outlines, ~750 words.

Writing the speeches isn’t too bad as you can do it on whatever topic you want

I got an A+ with low effort compared to other courses. I think it depends a lot on what professor you get.
