Learner Reviews & Feedback for Precalculus: Mathematical Modeling by Johns Hopkins University

Great course, great instructor. However, there is a problem with quizzes. The answers written in latex is a problem. It took me 2 months to finish the final quiz since I stuck in 1 question and couldn't find how to write the answer. Please fix it because based on other comments, students are really discouraged.

In general, it is good for me to recall what I have learned in school. Love the small story, such as cosine is strong especially with the accent. Those little human spark time warm the equation.

For the 3rd course, it is a great wrap-up for the specialization. I love the amazing story and how to provide an accurate estimation just through the dimensional analysis. I believe it will inspire people to explore the beauty of math. It worth all the effort!

There are some minor mistakes in this specialization, and I have provided all my findings. I hope it helps.

Had a blast through the course. Everything is thoroughly explained. Examples given for better understanding before quizzes are more difficult then the questions in the actual quizzes, hence quiz questions feel simpler and easier. I have learned a better way of judging a set of statistics then I had before. I would totally recommend this course to anyone looking forward to improving their comprehension of set of data.

There are errors within the quizzes.

Very good basic course for PUC level. Explanations are crisp and to the point.

This course help me a lot about modeling. As a IB student, this course is not very difficult to me. Actually, it didn't use calculus a lot but it is really useful on modeling.

Some tests are difficult to understand due to lack of explanation in problems or questions.

Nice course.

I am not sure how to describe the course. It is definitely NOT for non-math people. Not recommended for those expecting to be taught math. For those with advanced knowledge it maybe a good course to review the subject. The staff almost never answer the forums, and the quizzes almost never show the rubric, so doubts and questions go unanswered. I also don't think certification is meant for resumes either, so, again, I am not sure how to describe it. It is interesting though.
