Regarding a Reference textbook

Are the concepts taught in the course are enough if we score more than 90% in the tests? Or are there any additional concepts to learn? If yes can you suggest a reference textbook for the Data Science Course.

This course curriculum has been refined from some of the best textbooks out there for data science, though the topics are enough, you need to practice as much as possible.
You can compete in various kaggle competitions. Practice details will be shared by the time we reach some good handson part forward in the course.
