Sally is the best instructor in this course so far. The content itself started of great but I feel it didn't cover enough data cleaning techniques in the second half of the course. Still recommend!

Solid course with good examples and practices. The extra resources are very helpful and allow for additional practice. Even as a more experienced user it is helpful to refresh the core concepts.

Great course for the beginner! Only thing that I wanna see in this course in the next edition, if there is any, is the a bit more practice content. Overall great content with legendary tutors.

Excellent course. I enjoyed working through the BigQuery examples alongside the instructor. The career section was useful and it's worth spending time watching the Kaggle conference videos.
