Where you'll meet this parabola

Every thrown ball, water fountain and long jump traces one — and a satellite dish is a parabola too, focusing faint signals onto a single point.

Without quadratics: you couldn't predict where a projectile lands, and no dish could focus a signal — no satellite TV, GPS or radio telescopes.

Built for Alishba & Inaayah.

And for every CBSE student who'd rather try first and see what happens.

Learn by doing

Drag a light ray and watch it bend. Tilt a beaker and see the reaction. Every concept has a moment you actually play with — that's try karke dekho.

Adaptive practice

Half the CBSE paper is now competency-based. We drill exactly that — case studies, assertion–reason — and keep finding what you don't yet know.

Buffy the cat

Buffy, your AI tutor NEW

Meet Buffy — our real family cat, and now your study buddy in tribute to him. He gives hints, not answers, explains any concept your way, tells you which model answered, and is awake at 11pm before the test.

Maths Sprint NEW

90-second maths races against Buffy the cat — generated fresh for every grade and chapter. No sign-up needed.

Classroom NEW

Sit in on a live class — Buffy teaches, classmates chime in, and you can jump in with a question anytime.

Stuck at 11pm before the test?

Buffy hints, never answers. That's deliberate: the marks come from the thinking you do yourself. Three moments, replayed:

Meet Buffy in any lesson →
Class 4 Why does the moon look different every night?
BuffyIt circles us while the sun lights one side. Look up tonight: is the bright part growing or shrinking?
Class 8 Why does a straw look bent in a glass of water?
BuffyLight changes direction when it enters water. So which part of the straw are your eyes really seeing?
Class 10 I keep messing up the sign inside b² − 4ac.
BuffySay it out loud before you write: b squared, minus four, a, c. Now try b = −3. What does b² become?
New AI help — now live.

Buffy now streams his thinking as he hints, and a new Study Recommender reads your real progress to show exactly what to study next — never a made-up score.

CBSE now rewards thinking, not memorising.

From the 2024–25 session (CBSE Circular Acad-30/2024, carried into 2025–26), half of every Class 10 board paper is competency-based — case studies, source-based and assertion–reason questions that test whether you can apply an idea, not recite it. Memory-heavy long answers were cut back. This portal drills exactly that.

50%

Competency-based

Case-based, source-based, assertion–reason and application MCQs — questions that ask you to use the concept.

20%

Objective (MCQ)

Quick select-response questions, spread across every chapter of the paper.

30%

Short & long answers

Down from 40% — less reward for pure recall, more for clear reasoning you can show.

Based on the 80-mark theory paper (+ 20 marks internal assessment), CBSE Circular Acad-30/2024. Always confirm the latest scheme on cbse.gov.in.
