Course exam Q6's answer is (not) wrong <-edited I missed "pick the **incorrect** answer"
I have had several issues with the way questions are worded, and have found several places where the answers to the question is wrong. In particular there are two on the practice exam and one on the final exam. Question number six is below:
Then for question 3, one could think that you wanted to see the record label start dates, current, previous, and prior for each individual artist, so I wrote that query. Since I had only 30 minutes to do this quiz I did not get a chance to look through the data before jumping in and writing queries. You spend so much time detailing how to work with DATEDIFF() in the instructions when you could have been clarifying WHAT it was you wanted queried. I have commented several times about being precise. In data science and analysis, you either need to be very precise in what you are asking about or, you need to be available to answer questions. A good data scientist ask questions, we do not guess. I am here trying to level up. I am trying to get a job, but here I am providing feed back and reporting bugs and not only not getting paid for it, but actually paying to do it.
Creating exams is more than just finding good problems to solve, it involves adjusting the language of each question as you get feed back. It is not a set it and forget it kind of activity. You need to keep up not just with questions but with how people are interpreting your questions. I spent 20+ years teaching and even though I taught many of the same classes over and over, no two exams were exactly the same because I took the data from the previous versions and addressed the issues with the exams. PLEASE DO BETTER. PLEASE HIRE SOMEONE TO TEST YOUR PRODUCT.
Having fewer bugs means you earn more credibility and people like me can then report to the world our expert opinions on the level of care you use for your platform. Please contact me if you need help with this.
Thanks for reaching out.
Regarding Question 6, please read carefully the task and try to do it again.
Regarding the other questions you've expressed doubt about - we will revise the exams and get back to you.
Hope this helps.
ugh... in a timed exam where a lot of stuff is going on switching between picking the correct answer and the wrong answer is going to catch people every time. But, is that what you are trying to do? What was the intent of this problem? Was it to see if people can capture that one word out of many? Is there a way that you could fix this so that people don't miss that one word? Many students think that tests are built to find ways to trick them, to find ways to catch them making a mistake. I think tests are a way to gauge the amount of understand you have at a given point in time. I learn from my mistakes and I move forward. I will be reading for "pick the correct" v "pick the incorrect" answers in the future. But, what is your philosophy here? Are you trying to trick or are you trying to capture information? (rhetorical)
a bold "incorrect" would help people register that this question is asking something different than all the other questions.
