The content is interesting, but the layout of information is not great. It would be good if notes were provided. I found myself often going to other sources for reference. Navigating through these videos is not the best way to review what was covered. One can read much faster then one can serach through a video - especially when there are mutliple videos to be serached through.

There were several questions in quizzes that were not possible to solve, based on the lectures. I needed to google. Other times, I'd get a wrong answer, and I have no idea what portion is wrong. One time, the feedback was that, the answer would be correct if I had the correct sign in one term. I changed the sign, and it was still wrong.

Contents are good and the lecturer presents them in a clear way. Nevertheless, there is no response from the professors on the forum and the automatic grader doesn't work very well (it might give you a wrong answer just from rounding up). Solutions to the exercises should be provided at least once the quizzes are approved with 50%.

Overall the content was good. And it provided an initial path on how to go about optical designing. I sometimes feel the course does not have enough support to clarify my doubts. A chat box where a course candidate can clarify the doubts will be of great help.

The course was good however there are few things that stood out.

1) Notation and use of mirrors wasn't well explained

2) Quiz emphasis was more on solving algebra equation rather than hands on practice

3) Not much support on forums

Good info - but assumes a decent working knowledge of optics. Learned quite a bit from the capstone project, but the exam was rough (lots of curveballs).

Some of the online presentation and in-class quizzes need to be reviewed. Also, a few more worked examples can help cement the sign notation better.

Modelling tools are only available for CU students, so only a narrow audience can actually benefit from the course.

It was not easy to pass the course as the materials given is not in the level of the assignments!

This course took me months to complete because of messed up recognizing the answering system.

The worst course in my life. The first lecture was about the history of optics. After the lecture, you need to calculate the optical wavefront and angle of rays. However, no one gives you equations and how can you calculate it. You serious? There is no references and information where can I find the information. Don't waste your time and try to find another course.

Best regards,

Too difficult, I've never expected at this level. They didn't teach detail, and told us to complete the assignments. If someone can pass the homework, it's actually no need to take this class IMO.

I give up at first week. I hope other people get suceed in this class. I'm down. I'm too stupid for taking this class. The course makes me furustrated a lot !
