  2. Specify why you import each library

    It is not clear which library to import for each case. Could you add a note saying: "we import Pandas for xyz reason"... "we import scikitlearn for xyz reason" and so on. Otherwise, I just have to learn blindly.

  5. Select All

    Selecting Multiple file is a hassle, if I want to upload/move/delete multiple files at once I have to select them one by one which is not productive.

    I suggest "Select all" button and cursor selection feature.

  10. 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??????

  11. 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.

  18. correct grammar on ML0120EN-1.1-Review-TensorFlow-Hello-World.ipynb

    ML0120EN-1.1-Review-TensorFlow-Hello-World.ipynb

    After block 4, it says "it's" in a place where it should say "its", because it is a possesive, not a contraction of "it is".
