Educational tools

What each tool is for

The Science Quiz and Flashcards tool has practice questions in Biology, Chemistry and Physics, organised by topic for secondary school students preparing for WAEC, NECO, JAMB and Post-UTME. You can quiz yourself with explanations after each answer or switch to flashcards for revision, and it shows which topics you get wrong most often. It runs in your browser.

The Math Animator is for teachers and students who want a short animated explanation without learning Manim or a video editor. You place shapes, equations and graphs, add animations like fade, move and transform, and export the result, all in the browser. It borrows the vocabulary of Manim (FadeIn, Write, Transform), so if you later move to the real library, the ideas carry over.

German Language Learning drills translation between English and German across CEFR levels A1 to C2, with hints and vocabulary suggestions as you type. Answers are scored for accuracy rather than marked simply right or wrong, since there is usually more than one acceptable translation. The core practice works in the browser; its AI conversation and speech features call the server.

Picking one

If you are revising for an exam, start with the science quiz and use the weak-topic breakdown to decide what to read next. If you are preparing a lesson, the math animator is quicker than slides for anything that moves, like a function changing or a shape being transformed. The German tool works best in short daily sessions at your current level rather than jumping ahead.

For teachers, the science quiz works as a quick warm-up on a projector: pick one topic, go through a handful of questions together and talk through the explanations. Math Animator exports a WebM video, which plays in modern browsers and most slide software, so you can prepare an animation once and reuse it every time you teach that topic.
