  2. redesign your web UI

    You need a good UI designer working with courseware designer to improve the UI. Your web generally is slow and the two tabs (video vs review/test) are confusing. Their icons are confusing, too.

  7. Option to retake course exams if failed should be there.

    There are those who have failed the course but after retaking the course cannot re-attempt the course exams. By not allowing those to retake the course there is no way for them to obtain the Hadoop 101 certification. Does not seem ethical. This needs to be readdressed.

    Improve dashboard to show icons & small details with learning paths so that user can envisage where he stands. Also completed one's (where certificate / badge is issued) can be marked in green / shown with tick, inprogress can be shown as Yellow, pending can be shown as orange

  10. remake all tests and exams

    They look like they were made by a drunk person, all of them. I finished 7 of your courses, and they all look this way. A lot of grammar mistakes, questions unrelated to the course material (have to google to find the answer), answers like "All of the above" in the upper position (nothing is above), answers like "[something]", "[answer that is incompatible with the 1st answer]", "All of the above". I also noticed that if there is "All of the above" present, it's the right answer most of the time. The tests also have a lot of questions with…

  12. This question seems to have an error

    This question:

    SERVER OBJECTS (1/1 point)
    Which of the following is NOT a candidate for an object in the activities we defined for the host?

    Seems to have carried over the word "host" at the end from the prior question "Host Objects". The question probably should read:

    SERVER OBJECTS (1/1 point)
    Which of the following is NOT a candidate for an object in the activities we defined for the server?

  14. Errata on NUMPY 1D ARRAYS Video (Wrong Hadamard product)

    The video miscalculates the hadamard product of two arrays. [1, 2] hadamard [3, 2] should equal [3, 4] and not [3, 6] as the video suggests.

  16. Courses on natural language processing

    Hello,
    Everything on cognitive class has really proven to be the best of all courses to me. I have a small suggestion, most of the courses are related to data science but there is not much on natural language processing. I request you to add some courses related to the subject.
    Thank you

    The Website was down/not accessible last night, when I am in the final exam of PY0101EN, please help me to reset my final exam result.
    Then I need to attend the final exam again and win the badge.
    The current result only shows that only 20% result was submitted and recorded.

  20. Retake Exams

    The point of this site is to learn and I find it ridiculous that you cannot retake a course if you fail it. That does not encourage users to learn it only teaches that you should get it right the first time or quit. I now understand what I did wrong and would like the chance to prove so and receive the badge.
