Greetings,
As per $subject, there is a new course that I've published which has recorded sessions and live QnA classes. As a beginner, you'll get to know everything about tableau from the perspective of Business Use Case so that you can better understand tableau with practical questions / scenarios.
Below is the link for course details, fees and time details.
Special Note - This course is free for students who have already attended my Tableau Dashboard Classes. Hope it will help you as a good refresher.
