Get help with Science and Technology, Secondary 3
Most tutoring makes you sit through material you already know. MapleMind flips that: pick the exact skill that's causing trouble — any of the 34 below — and the tutor teaches just that one, step by step, as many times as it takes. Ask questions in plain words, any time of day, in English, French, or 12 other languages.
The official Quebec Science and Technology, Secondary 3 curriculum
Quebec defines Science and Technology, Secondary 3 by strands and outcomes. MapleMind teaches the same curriculum reorganized for one-skill-at-a-time tutoring — the table shows exactly where every official strand lands, and the ministry's own wording is quoted under each unit below.

How MapleMind teaches Science and Technology, Secondary 3 — every unit, lesson, and skill
Every skill below runs as a short session: a plain-words lesson, a worked example, solving it together, then a five-question skill check that earns up to three stars. Guided Mode keeps it teaching instead of answer-handing — turning it off needs a parent's password.
