How can a coaching institute run online mock tests with negative marking?
In QG Playground, write the test yourself or generate it with Granny from a chapter, then set it as a scheduled quiz with a time window. Choose minus marks of a quarter, half or a full mark, which never take a total below zero, and add a whole-test timer. Decide whether students who started can finish after the window closes. Switch on the question bank so each student gets a different set drawn from your categories, with the easy, medium and hard mix you choose, which stops answer sharing in a batch. Give each batch its own link and window with groups, and use tab-switch detection to discourage looking things up. After the test, the report ranks every student by score, correct answers and time, shows the hardest questions for your next class, and exports to CSV. Projects follow a batch across the whole test series with an aggregate leaderboard.
