Wonderful, the paused pace is perfect, allowing the new chunks of information to sink into the brain as due and the visualizations themselves are truly effective. Thank you so much for this!

Will you be releasing AS and A level content in the future? I discovered your channel in January and helped me get three A*s in Biology, Physics and a Chemistry so I would really appreciate it if next year you made content for Physics and Maths AS and A level as I’m thinking of choosing those subjects!
