Editorial Policy

How the free courses and guides on this website are written, checked and corrected.

Who writes the lessons

Every course follows a study guide written by Ravindra Bagale for his own online and offline batches. The order of topics, the labs, the warnings and the tips come from his classes, and the "Ravindra Bagale's Tip" boxes describe mistakes his students actually make.

Sample data

Examples, labs, templates and dashboards may mention real companies and apps (for example, “Suppose we are a junior analyst at Flipkart”) so the situation feels real, but the numbers in them are sample data made for teaching, not real company figures, and lessons say so. People in the examples are fictional. Real public incidents are clearly labelled and come with a source.

Dates

"Last updated" on each page is the date its content was last changed, not the date the site was rebuilt.

Corrections

If you find a mistake, send the page link on the contact page channels. Mistakes are fixed on the page itself.

Advertising and independence

The site may show Google ads. Ads do not decide which topics are taught or what a lesson says, and no company pays to be mentioned in a lesson.
