Questions and answers

A free exam-prep tool. Give it a topic, a lecture, a chapter, text, a photo, a PDF or a Word file and it creates one study pack: A&R questions, important questions, notes or a cheat sheet. You can download it as a PDF.

A&R means Assertion and Reason. Each question has two statements. You decide whether each is true and whether the reason correctly explains the assertion. They are common in CBSE and other board exams, and in competitive exams.
