HIGHLY recommend. Each question is centered around something that must be known for the PROFESSIONAL-DATA-ENGINEER exam. Each answer is clear, concise, and contains all needed steps in a manner pertinent to the subjects. One thing need to be improved is there are no explanations for each question. Only explanations for some questions. It would be better if you give explanations to every question.
