Frequently Asked Questions

Everything you need to know about using Curiosity for NEET prep

[Q.01]What makes Curiosity different from paid NEET prep apps?+
Curiosity is engineered strictly for cognitive retention, not ad monetization. Most apps want you scrolling endlessly. Curiosity is designed for micro-targeted, distraction-free practice. We offer adaptive spaced-repetition testing, a live multiplayer arena, shared study circles, and an AI doubt tutor — all completely free, with zero ads, zero tracking, and no paywalls.
[Q.02]How does the Smart Recall algorithm work?+
Smart Recall is our proprietary adaptive learning engine. Instead of practicing random questions, Curiosity splits every quiz into a scientific mix: 30% Unseen Core (fresh NCERT questions), 25% Weak Syllabus Areas (under 60% accuracy), 15% Spaced Cognitive Reviews (past correct answers at risk of decay), 10% Personal Notes integration, 10% Saved Bookmarks integration, and 10% Community AI Doubt questions. This ensures complete personalization tailored to your direct syllabus exposure.
[Q.03]How is the platform 100% free with no ads? What is the catch?+
There is no catch. Curiosity was built as a clean, high-performance initiative to support medical aspirants who want an elite focus sandbox. We leverage highly optimized serverless architecture, edge database systems, and lightweight API models to keep server overhead virtually zero. We do not show banners, run trackers, or block core features behind paywalls.
[Q.04]Are the MCQs mapped to the latest NCERT syllabus?+
Yes. Every single one of our 10,000+ MCQs in Biology (Botany & Zoology), Chemistry (Organic, Inorganic, Physical), and Physics is tightly mapped to the NCERT guidelines and standard NEET weightages, including high-yield previous year questions (PYQs).
[Q.05]Can I study with my friends or batchmates?+
Absolutely. Curiosity includes two multiplayer systems: Invite-Only Study Circles (capped at 30 members) where you can sync streaks, co-edit shared formula sheets with presence detection, and clone notes; and the Live Duel Arena, where you can host real-time MCQ speed races with lobby codes.
[Q.06]Does it work well on mobile devices?+
Yes, Curiosity is a mobile-first Progressive Web App (PWA). It works seamlessly in any mobile browser on iOS and Android. You can also add it to your home screen for an app-like fullscreen focus experience.
