I am not sure why Johns is even teaching a course on World Politics if she cannot remain unbiased. She explicitly said "I love Israel" in lecture -- not that her opinion on this matters to me, but bluntly taking a side in the middle of class gives away her bias and also made a lot of students I knew in the class uncomfortable.

I believe this is why she doesn't record her lectures or post any of her lecture slides, because half of the content is her personal opinion and many times incorrect.

If you do not read historical and political accounts on your own time, you will leave this class misinformed and brainwashed by Johns' politics. Only take this class if you want to be indoctrinated.

Professor Johns makes international law (a topic that could otherwise be sort of boring/irrelevant) pretty interesting- her lectures are engaging and extremely well organized. There are weekly quizzes in section that are super easy, just set aside 20 minutes or so to read the cases and you'll be fine as the questions are simple fact based questions. Her midterm was a bit harder than I expected actually, but she does curve it generously and I really should have just studied more. The tests are worth most of your grade (70%) however given COVID-19 our final was changed into a set of essay questions that were take-home. The take-home final took a significant amount of time and although I respected her as being fair during the rest of the time I took the class I think she could have been a little more understanding.

While I agree with other reviews that have said some rather unpleasant things about Professor Johns, the class itself is not hard. It is true that the professor does not post lecture slides (if you need them that bad, go to office hours with a TA) or study guides (again, ask your TA to cover things you don't understand in section), the class is pretty straightforward. As long as you do your job as a student and attend class, and read the assigned book, I think you should be fine.
You are assigned reading quizzes for every chapter you cover (open note).
The midterm/final is MCQ and then SAQ. While she will say to be brief, DO NOT BE BRIEF. She will make you underestimate the exam and reassure you that it is a breeze. ITS NOT it's UCLA, you will need to study. You do not have to write long paragraphs, but ensure you are using the right vocabulary and answering the questions fully. I recommend studying the vocab so you can try your best to hit all the "key terms" she asks TAs to look for.
I don't believe that Professor Johns is mean or thrives from watching students fail. She is old school. She believes that her only job is to teach and go home. You definitely have to pull your weight. Go to class, read the book, study, and you will be fine.

While this class is manageable in workload, it is clear Professor Johns is the kind of teacher that does not want her students to succeed. The content of the class is interesting and relevant, yet Johns teaches it in the most frustrating way possible. Although her exam questions aren’t inherently difficult, she instructs TAs to grade them with such extreme specificity that anything except for textbook definitions are penalized. This led to the midterm class average being a D, which is absurd for a class with mostly straightforward content. Not only that, but Johns makes basic resources entirely inaccessible. She refuses to posts lecture slides online and doesn’t even provide them to the TAs, leaving both students and TAs totally lost. This class is doable if you keep up with the reading and attend every single lecture, but Johns’ grading and teaching styles make a very interesting class unnecessarily demoralizing.
