She will never tell you when solving problems which procedures you have to follow beforehand and will punish you severely in the tests if you don't know those "rules". Even if you thought you've a strong foundation (A+ in STA247 from a different prof) and learned very hard for the test you are still very likely to get a 60 in her test.

As long as you were honest with yourself when watching the homework videos and were listening during lecture it should be smooth sailing.

I know Professor Wong gets a bad rap but she's actually not the worst prof in the stats dept lol. She provides really good slides and is always super active on piazza which you don't get a lot from other profs. Her assignments/tests are pretty hard but honestly if you do the textbook questions they aren't too far off.

What you read in the other reviews is not wrong. This professor has little compassion for students, regularly dismissing concerns even though they "welcome" any emails about those matters. According to them, successful students are an anomaly and a reason to adjust the entire class down. You won't have a choice of profs for this course, good luck.

Prof. Wong was a great lecturer. She explains concepts that may sound very intuitive. Do pay attention to her explanations since they will definitely be tested. Don't let the MCs scare you (they're really reasonable). Do your work, complete the Modules, retake the quizes as much as you could, and an A will come naturally.
