10th grade — proofs, chemistry, and picking a direction

Geometry proofs, the first chemistry that needs real maths, and the year most students work out which subjects they will carry. Study tools are open now; the guided Academy subject paths are still in build and we say so on every one.

Questions

What does Koydo Academy cover for 10th Grade?

Math, English, Science, Humanities, Computing. The revision toolkit — 350+ browser activities including flashcards, notes, a focus timer and subject deep-dives — is open now. Guided lessons, scored practice and mock exams are still in development, and the coverage roadmap shows exactly where each subject stands.

Is 10th Grade the right level for me?

10th Grade on Koydo Academy is written for ages 14-16. Academy covers ages 14 to 18; if you are younger, Koydo Learn covers ages 11 to 14 and there is a Koydo for every step below that.

Do I need an account to look around?

No. This page, the coverage roadmap and the activity library are all open without signing in. An account is for saving progress and for anything a parent or guardian needs to manage.

How does this fit alongside my school syllabus?

It is built to sit beside it, not replace it. The study tools work with whatever you are already being taught, and the subject surfaces let you go deeper on the parts that are not landing.
