Subject battle

Start a Biology battle.

Battle Mode will use the Arena engine for the live challenge. Progress still comes from answered questions, mastery repair and real revision sessions.

Syllabus context

Biology stays visible before the first answer.

Skill result

Accuracy, explanation review and weak-topic repair drive progress.

Fair progression

Cosmetics can change style. Learning still decides strength.
