Save yourselves and don't take her.

Rating: 2.0/5, difficulty: 5.0/5
She's ok but going to her class was literally useless since her accent makes it hard for people to understand her and she makes simple concepts more complicated than they actually are. I rarely went to her class and did fairly well just by doing the textbook questions. If you are someone who struggles at math I suggest taking someone else.

Religiously following the textbook, even if you know how to answer perfectly and u have not practiced the textbook, you WILL fail.

Jessica is a wonderful professor.
She is patient, friendly and caring. I contacted her a few years after I finished her math class, and she was still willing to help me. 
I believe her teaching is meticulous, and the class handouts are incredibly detailed. I believe that if you adapt to her teaching style, you will achieve high marks!

Very difficult to learn from. Explains in a very difficult way to understand and her accent makes it more difficult. Going to class was useless for me since I never understood a word she said and her notes are sometimes difficult to understand as well. Final was brutal compared to midterm...

Jessica was okay but her exams were way too easy compared to the final for the course.

Some people say she sucks at teaching, but I think she teaches math quite well. I'd say the reason why midterm averages are low is because most students don't study enough. As long as you do all the assignments, you will do fine in the course, since the tests and exams are similar.

Accent made lessons harder to follow but the notes were easy to understand. Homework heavy & quizzes are much easier than exams. Rarely paid attention in class & failed a midterm but passed overall, marks are easy to get (points for work even if your answer is wrong). Reviewing notes and doing HW/textbook questions is key.
