    The material is full of errors, words missed or typed twice. Obviously, it's never been proofread. There is no way to ask anyone a question; no way to talk to the tutor; no student forum. Right at the end is a test where you have to select code snippets but you can't run the code, there is no way to test it. What a weird course! I would not recommend.

    The pinnacle of the course is to take a 20 question exam where you are expected to select code snippets that meet the questions definition. Some are multiple choice and the rest are single answer. This is not a good test of the course material as many of questions were not covered in the course. Additionally, there is no sample data to test our your answers.

    Finally, it is filled with errors, for example it asks you to provide month year from a timestamp. Yet all the questions only have month and day. Good luck guessing which one they meant.

    Skip it. You'd be glad you did.
