I am a Maths, Physics and Chemistry tutor. I believe in visual learning, that as humans we have always responded better to visual stimuli rather than textual resources. This is down to basic evolution, as we have existed for hundreds of thousands of years, but writing only came around in the later portion of our existence. Many of my resources resolve around this concept with the idea of using posters to remember information. Feel free to use them as templates to create your own!
