CollegeSpends 30+ minutes of each 75-minute lecture wasting time instead of doing examples. Lectures are strictly theory and provide no help with actual word problems. Be prepared to study a lot.
Good professor overall, exams were very fair and similar to the homework. She also made a great final study guide. I understand the frustration of others with the extra credit not really helping anyone's grade, but not sure why the reviews are so negative otherwise. She is an overall good professor. Clearly cares about students if you talk to her.
Many comments here give Ravat a low grade, but I do think she is a good professor. Her lectures are easy to understand. As long as you fully understand the course materials and assignments posed on canvas, you'll find that the mid-term and the final are not that hard to do.
Low quality lecture, don't expect to understand anything in class but take ton of your time ahead exams to understand yourself. Low quality office hour, not even good as ULA or TA. Uncleared grading and fake promise in extra credit. One of the WORST professor I ever had. Stop complaining like a baby in class about the rating you get from students
Disappointed. She acted like a caring professor offering lots of extra credit assignments which was heavy, but they are totally fake that does not helped with your final score. Not telling you how much extra credit will be added. Said will add more credit to midterm but nothing is real. Will never take any course with her and she disgusted me.
Took pstat10 and 120b with her and I would say her classes are easy if you do the work. HW and quizzes are good practices for exams. final was almost the same as the study guide and a cheat sheet was allowed. Personally think midterm was harder due to shorter test time
