How it works

See it. Solve it. Keep it.

Watch the lesson, solve the practice mission, keep it with spaced review. Every topic gets one short visual lesson and one practice mission, then Medha brings back what you missed until it stays.

1 · See it: the lesson

One teacher, one student, one topic.

  • 15 to 20 minutes, set by how deep the topic is, never padded.
  • The teacher's pen draws circles, arrows and steps on the diagram as the voice explains.
  • Think pauses ask you to predict before the answer is shown.
  • A worked exam problem in every lesson, with the common wrong turn and how to spot it.
  • A map of where you are and a line telling you what comes next.
  • English voice with English and Hindi subtitles. Formulas stay as they are.

THINK BEFORE I SOLVE ITDoes the ball take longer going up, or coming down?

2 · Solve it: the practice mission

Six steps, always in this order.

Each step depends on the one before. The mission uses only what the lesson taught, so there are no surprises and no gaps.

  1. 1DecodeWhat is this?Acceleration in one picture and two lines.
  2. 2QuizCan I recognise it?Which graph shows constant acceleration?
  3. 3RecallCan I say it from memory?Write v² in terms of u, a and s.
  4. 4PredictDo I know what happens?Drop it from twice the height. How much longer does it fall?
  5. 5SolveCan I work it out?A car brakes from 72 km/h to rest in 4 s. How far does it go?
  6. 6ExamCan I do the real thing?Past JEE and NEET questions, with the year shown.
3 · Keep it: spaced review

What you miss comes back.

A missed question returns after 1, 3, 7 and 21 days. Your home screen shows what is due today, so revision is a short daily habit instead of a panic in the last month.

STEP 4 OF 6 · PREDICT · TRY IT

A stone dropped from a height h takes 2 s to fall. Drop it from 2h. How long does it take now?

Every answer is computed before it reaches you.
4 · Accuracy

Every answer is checked before you see it.

Computed, not typed

Every numerical answer, and every wrong option, is worked out in code, units included.

Wrong options with a reason

Each wrong option comes from a real mistake students make, and the explanation names it.

Checked against the source

Every topic maps to a line of the official syllabus and every fact to a standard textbook, page recorded.
