View ChannelAbout
Hi - we make video lessons for science and maths, aiming to give a concise run through of everything you'll need to know for your exams. Each video has been designed specifically for the 9-1 GCSE courses, and although they most closely mirror the AQA spec, everything you need to know for the main exam boards will be covered. We also have a website where you can work through the lesson videos and answer a series of practice questions to check you know all the required learning points. All your progress is automatically tracked, and you can sign up at www.cognitoedu.org Best wishes, Amadeus & Tom
