    • Hadoop 101 Training class

      The instructor Ms. Desai was very fast with the material presentation and a lot of her words are muffled and hard to understand. The video did not stay on slide long enough for students to view it and the next one pops up. One of the worst online class I have taken

      • There should be a way to re-attempt the final test.

        I have attempted for one test and was failed to score 60% mark. I have prepared for the exam again , but there is no option for second attempt.
        You should provide option for re-attempt after 10 days or some limit.

          Thank you all for your suggestions. We allow re-attempts for exam questions on legitimate case by case basis only. Rather than post your request here, kindly open a Support Ticket with your request. To do so, go into the course for which you want to re-attempt and click on the blue “Support” button in the middle right of the page and under “Contact Support” enter your request mentioning the course and a justification. Please be patient as it may take a few days to review your request.

                • 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.

                  • Re-attempt on courses

                    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
                    Mubashar

                                        • Hadoop 101 course

                                          The course has good content, but the instructor is just reading the lines instead of trying to explain them meaningfully. It definitely needs improvement. Please look into it.

                                          Thanks.
