IELTS / PTE / TOEFL speaking with an honest band score.

Arithmetic & equations, checked by code not vibes.

Science (NCERT)

Light, electricity, the human eye, environment — from the textbook.

🧪 Interactive labs

See it, don't memorise it — every move is checked by a real engine.

Solve equations move-by-move — every step checked.

Concave mirror — find where the image forms, and how big.

Myopia or long-sight? Slide the lens power until the chart is sharp.

Equation Balancer

Set coefficients until the atoms balance on both sides.

Probability Spinner

Recolour the wheel to hit an exact probability — then spin and see.

Coordinate Geometry

Plot points; hit the midpoint & section formula exactly.

Add reactant until the exact mass of product forms — via the mole ratio.

Cross two parents; get Mendel's 3:1 ratio, proven by the grid.

Slide the object; watch the image form on a bench.

Bend a beam across glass — Snell's law, and total internal reflection.

Circuit Builder

Series, parallel & mixed — Ohm's law computes the current live.

Set angle & speed; watch the arc — hit the target flag.

Drip base into acid — watch the pH jump at the equivalence point.

Heights & Distances

Tilt the sight-line — tan θ = h/d gives the tower's height.

F = BIL, and Fleming's hand — set the force, read its direction.

See-Saw (Moments)

Slide the weight until moment = moment and the lever balances.
