In partnership with Revision Ninja
Lesson 3.1.2, Produce 3D CAD assemblies of components: 20 multiple choice questions for the OCR Engineering Design (J822), Unit 2: Communicating designs, written with Revision Ninja.
Host it live on the board and students join with a game code on their own devices, or revise alone with Free Play. The answers are revealed in the game.
