Instructions are less clear than the 3 previous courses, but the discussion forum helped me very much.

The "python" assessments should be more descriptive. It says "Please enter your Python code in the space below the assignment instructions.", which is simply wrong as I had to figure out hours later after trying pretty much everything. And the downloaded book file has some strange characters which don't seem to work fine when using Windows. Had to work around this.

Good one with lots of knowledge packed in, in term of handson it could have been better.

The elastic search assignments are too confusing.

Too Easy, just junior level

lack of support ,bad exercises
