  1. Fix Connectivity Issues

    I understand the convenience of these tools being cloud-based, but they continually have connectivity issues or lag. There are massive disruptions and it's a huge hassle or it's very frustrating to lose work. The quality of the course suffers.

  3. Remove error in function r2_score

    r2_score first argument is the true value and the second one is the predicted value, so the code should be corrected.
    Thanks

  12. I suggest you require prerequisites before allowing anybody to enroll in this program

    Taking the data science classes by anybody unfamiliar with any of the basic programs used during this course makes no sense. It's monumentally frustrating trying to figure out the basics like this:
    Exercise 3: (Jupyter notebook)
    2. From the menu, click on "Insert", then "Insert Cell Above" or "Insert Cell Below".; While it's clear how to insure one or the cells, it's difficult to figure out how to enter the second now.
    3. Note you can use the keyboard shortcuts: [a] - Insert a Cell Above; [b] - Insert a Cell Below. Really? What am I suppose to click on??????

  13. Not always so clear on when I have a correct answer

    Your user interface doesn't always make it clear that I am correct. Also adding print(xxxxx) to the answer when you're asking for output shouldn't be counted as wrong.

  17. My Courses section should be divided in Completed and In Progress.

    Additionally, a progress bar would be nice to have and a feature to resume learning from where you left off.

    So, please update current version of Seahorse.

    Thanks for your efforts in putting together such a wonderful environment.
