    Short lessons, clear tasks and an instructor who answers questions in the community within a day. I finished in five weeks.

    The projects are the best part. I used the final one in a job interview and it carried the conversation.

    Lovely pacing. A couple of lessons could be shorter, but the quick checks kept me honest the whole way.
