Why it exists

Most study sites ask for something before they teach you anything — an email, a trial, a streak, a plan. Meanwhile the thing you actually wanted was one clear explanation of one topic, right now, because there is an exam on Thursday.

Stupado is the version of that without the ceremony. Every page is a single topic written to be understood in one sitting, followed by a quiz so you find out whether it stuck. Nothing is gated, there is no account to make, and your quiz scores stay in your own browser rather than on our servers.

How we write

Four rules every lesson follows
🎯

One idea per page

A lesson explains a single concept properly instead of half-covering ten.

🗣️

Plain language

Jargon only when it is the thing being taught — and then it gets defined.

🧪

Examples over theory

Worked examples and the mistakes students actually make, not just definitions.

🔓

Open by default

No account, no paywall, no streaks to maintain. Open a page and read.

What a lesson looks like

1

The explanation

The concept in plain words, built from what you already know — usually under five minutes of reading.

2

Worked examples

The idea applied step by step, plus the common mistakes that cost marks in exams.

3

A short quiz

A handful of questions with instant feedback, so you leave knowing what still needs work.

Questions

Is it really free?

Yes — every lesson and quiz on the site is free to read, with no account and no paywall. There is nothing to upgrade to.

Who is it for?

Mainly secondary and high-school students revising a topic, but the lessons work just as well for anyone brushing up on something they half-remember.

Does it replace school?

No. Stupado is a revision aid — it explains one topic at a time so you can fill a gap quickly. Your syllabus is still the thing to follow.
