Revision posters (2 sides) containing everything covered in the Exchange Surfaces and Breathing chapter (3.1.1 in specification) of Module 3 of the OCR A Level Biology A (H420) specification. The handwritten posters cover the content required for the whole chapter (same chapters as those in the 2015 Pearson textbook) to the best of my knowledge (plus occasional extra details). I revise by completing practice questions using these posters which take me many hours to create; hopefully others will find them as useful as I have!
