This is a set of the Data Scientist Certification (Literacy Level) practice questions and the official reference book, 3rd edition (latest). I read it once, but no longer need it, so I'm selling it. The condition is quite clean, and there are no markings. The official reference book is the 3rd edition (latest). A considerable number of questions were taken from the latest exam scope, so if you're starting to study now, the latest edition is recommended.
