I have learnt quite a few things in this course. However, I will point out that you must be very attentive and not too surprised when you find a mistake, as they are common. I will leave aside the fact that there weren't many classmates around, which prevents you from having meaningful conversations in the forums and feedback on your peer-reviewed assignments, but I believe it is of interest to realize this soon enough as to not have unrealistic expectations. I was especially disappointed with the quality of the quizzes and other assignments: there were many mathematical expressions that weren't formatted correctly which made it very hard to decipher them. Apart from having badly formatted questions (containing spelling mistakes here and there), there are a few instances where even the answers gathered from the grading tools are wrong in some cases and at the very least ambiguous in other cases. I knew most of the material before taking the course and I was unable to achieve a perfect grade, partly due to the fact that there is absolutely no support from the teaching staff and partly due to the grading system used by the university. On the positive side, most of the videos were engaging in my opinion and all the concepts presented are directly useful to any computer scientist. I particularly enjoyed the first half of the course on number bases and modular arithmetic. Depending on your background, you may find the second half of the course somewhat basic, yet still useful. Overall, I would recommend other courses such as CS50 by Harvard University before this one if you are looking for a certificate. Otherwise, you can skip assignments, do not worry too much about the grades and learn important concepts from this course as a great mathematical foundation in computer science.

There are still some unsolved bugs of the grading system in the exam.

Some questions are wrong.
Tells us formulas but doesn't tell the proof of it.

I'm on week 3. So far so good. Challenging. Love practical tasks with implementation of steganography and cryptography.

still errors in quizzes after notification in beta-test. No-one from staff replies to comments or forums. I really want to give it 3.5, not 4

The content is very interesting and the professor is amazing.
But, the quality of the examinations could use some perfecting, although they are challenging and relevant which is a very good thing!

The professor is nice and does her best but overall the course is not structured well. Some hard to grasp assignments, assignments where you must collaborate with peers in loosely defined ways. Almost no feedback in quizzes. Failure in quizzes due to incorrect input format.

VERY VERY VERY Detailed class. The professor is very intense and makes you practice a lot to reinforce learning and has so many outside resources to supplement learning. She also encourages communication among class members which is cute. She is very passionate. This is the closest I have come to a real college class on Coursera, talking from actual college experience.

Pretty good teaching. My only complaint would be some seeming technical flaws with some tests that made a few questions hard to understand. They are either technical flaws in rendering the templates maybe, or I just couldn't understand the explanation.

The course was great with all perfect assignments and quizzes however I did like the 8hr penalty for each graded quiz. It was a long wait to take the graded quiz again which was quite stressful for me. Overall I would recommend the course to anyone who is just starting computer science or plans to revisit the basics of Compsci.

This wasn't what I expected from the description.
