Things worth putting on a wall

The cheapest revision there is — you look at a chart for months without meaning to. Designed for paper: big type, black on white, legible from across a room.

For a parent, the night before

One page

Not a section of this site — a single sheet meant to be printed or sent on. If your parents are worried and you do not know how to say any of this, send them this instead.

Class 12 Physics

A3 wall chart

Every formula the paper assumes you already know, on one sheet. Print it at A3, put it where you brush your teeth, and stop looking things up.

Class 12 Maths

A3 wall chart

The integrals and derivatives you are expected to produce from memory. Calculus alone is nearly half the paper — this is the half worth having on a wall.

Organic conversions

A3 wall chart

Organic is 26 of the 70 marks in Chemistry, and it is pattern-based — the same conversions come round every year. Chemistry is scored in half marks, so the reagent alone is worth writing even when you cannot finish the chain.

Nothing here is sold, and nothing needs an account. If a printed version would genuinely be more useful than a home-printed one, that is a thing worth making later — but it will never be the only way to get the content.
