EnglishWorld literature and writing that has to hold an argument across pages, not paragraphs.

ScienceBiology: cells, genetics and systems, with the lab vocabulary that comes with them.

HumanitiesWorld history — cause and consequence rather than dates to memorise.

ComputingFirst real programming, and what a web page is actually made of.

Questions

What does Koydo Academy cover for 9th 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 9th Grade the right level for me?

9th Grade on Koydo Academy is written for ages 13-15. 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.
