  1. I din't pass the final exam because of Internet Connection and...

    Question is I have bad Internet Connection, and when I was answering some questions I clicked check but web didn't show me results. I tried to re-click again. Lag worked at that time and my second click was picked by web and my second opportunity was spent. This happens to me many times, and happened to me when I was doing Data Science 101 exam.

    One suggestion I propose is disable double-check when the first attempt is correct.

    I had a 59% score in Data Science 101. That means I can't achieve the Data Science lvl1 and Data Science lvl2…

    • Button at the end of a screen

      It appears that previous/next button in the course content (ones which are visible when watching Lessons) at the bottom of a screen are not working.
      However, if my notice is not correct then it is not intuitive enough :) I think it would be great if I could easily go between lessons.

      Apart from that, as a new user I really like your platform. And please don't get my comment wrong way, as I'm currently working as a customer support engineer I know how feedback from users can be helpful (so, I suppose you'll receive few more from me, if…

        If you miss a review question after two attempts, the correct answer is still not shown, just a red x on the wrong answer. Please show the correct answer.

          • Review option about attempting the quiz

            Once we completed the quiz, it would be very useful if there is option to see which are questions we answered correctly and which we did not.

            • For Hadoop 101

              There are multiple complaints under discussions within this course regarding the speed in which the instructor speaks. Slowing down her speed within the video makes her voice unbearable. I get the impression that no one is reading the discussions or suggestions. Or, if someone is, we are being ignored.

              • Include an option to download certificates on the certificate page

                I was going through the Certificate page for the course "Predictive Modeling Fundamentals 1" and noticed that it would be good to include an icon /option where students can download their certificates

                • Download the course materials

                  I am trying to download all the course materials at one place. I found it is very much useful, it contains transcripts n materials, videos. I could not find the same for all the courses. For example, under the course 'Introduction to Scala" this tab is not present. "Download the course materials"

                  • Make it easier to enroll and see enrolled courses

                    I want to take all of the courses in the big data learning path in order. It appears that I must enroll in each course separately. I wish I could just enroll in all of the courses in the learning path at once.

                    Second, when I enroll in courses I see no way to tell which courses I am enrolled in.

                      • Course navigation

                        I'm taking the Getting Started with Data Science class and it is not clear how to move forward to the next lessson. I end up just going back to the overall course lesson outline and click the next class. It would be nice if there were a "next" button available after each lesson is finished.

                          • Fix exam wrong answer in DA0101EN

                            Question 20 asks what you should do if a model gives R^2 = 1 on train set and R^2 = 0 on validation data. There are 3 options, I tried to answer with 2 submissions and the obviously wrong answer (model works fine on test data so it has no issues) is the only remaining option.

                            Please fix this as some people could feasibly need this one question to pass the course.

                              Hello,

                              I see currently there is no way to re-attempt faild courses. it would be great if you add re-attempt like after 1 week or month. Maybe with different questions if possible.

                              Thank you.

                              Best Regards
