Hello. I was wondering if you could make videos on AS Level Edexcel Biology ? Because during IGCSE (I’m an international student), whenever I didn’t understand something, I always referred your videos and they were always so helpful! Now I’m at AS and I feel a little lost in certain topics (especially the Cardiac Cycle and it’s graphs!😫).
And I really like how you explain, and unfortunately my school teachers’ explanations aren’t that great for me...
Please consider it🙏🏽🙏🏽 it would help me and I’m sure a lot of others who watch you’re vids so much ! Thank youu☺️
