Keep your teachers, textbooks and classes. Use Smart Notes in the moments between them: to organise an idea, check your understanding and revisit what needs work. The three bars in our mark are these three steps.

A good-looking note still needs a reliable source. Our standard is simple: show the reference, explain the context, and make it easy to flag a mistake.
Read our content promiseLook for the named reference attached to a note. A general subject reference is not the same as a checked citation for every claim.
Foundation practice is a starting point. Planned coverage is labelled. We do not promise selection, marks or a complete syllabus.

Free foundation practice, flashcards and revision tools for SSC CGL, SSC CHSL, RRB NTPC and Bihar Police. These are starting collections, not complete exam courses. School and entrance chapter libraries are still being prepared.
You can start free practice in your browser without signing up. Anonymous progress stays in this browser on this device. Clearing browser data can remove it; it does not automatically move to another phone.
The core practice and revision experience is free. The Store is separate: you can choose a paid study pack when its contents and format fit your needs. Check the product page for price, preview and delivery details.
Foundation practice is labelled as practice. A question should be called a PYQ only when its exam, year and source are recorded. Always use the official syllabus and notices for your exam.
