Roy is honestly a sweetheart and she's a decent lecturer. The reason I didn't do so well in this class was bc I had a very difficult schedule and didn't put in the time for the class. If I studied more I could have gotten an A. I literally crammed EVERYTHING the night before and managed to pass. It's not impossible but its definitely not easy.

This class is hard just because there is so much material to cover. She does a good job of explaining concepts but reading the book definitely solidified concepts for me. Homework and test problems from the book, so use those to study. Put in the work and you can get an A

Lengthy homeworks every week, and extremely long labs. Labs are done in R but the TAs aren't helpful at all with understanding the material or going over functions to use on the labs. Exams are also hard.

I enjoy her class. But exams are difficult.

The class was fair. HW was not graded. There are weekly quizzes which help understand the material better. Lots of material to cover, try not to skip lecture. The final was fair, I realized later that every problem was solvable using the theory i learned in class. Logic. Intuition. Be very analytical for the final, trust your theory knowledge.

She doesn't know how to design the exam. The midterm problems all come from homework. But the final is extremely difficult that you won't figure it out how to solve a single question. Besides, you have about 15 to 20 questions for your homework every week.
