Frequently Asked Questions

Everything you need to know about the portal
Is this JEE simulator completely free to use?
Yes. 100% free with no account creation, credit card, or paywall required. All question derivations, CBT simulators, and revision notes are publicly accessible.
Does the simulator follow the official NTA JEE pattern?
Yes. The simulator mimics the official NTA computer-based test interface with standard section navigation across Physics, Chemistry, and Math, a 5-state color question palette, and +4 / -1 scoring logic.
Can I practice topic-wise questions without a timer?
Absolutely. Switch to Practice Mode from the top navigation bar to filter questions by chapter, year, and difficulty, and reveal step-by-step mathematical explanations at your own pace.
Are my bookmarks and notes saved offline?
Yes. Your bookmarked questions, personal study notes, and scratchpad calculations are stored securely in your browser's local storage so you can resume anytime.
