This video is for GCSE science and biology students who want to practice doing 6 mark questions. In the video we take a 6 mark question on the lungs, alveoli and gas exchange and deconstruct how to get maximum marks. With a focus on how to correctly address the command words, a lesson tutorial (with scientific animations) and then a lesson on how to structure the answer you will be getting 6 marks every time! The topic covered is for GCSE Science and Biology for AQA, Edexcel, OCR and IGCSE. If you found the video useful then let me know in the comment section or leave a thumbs up!
