Hi, Im looking at buying a A-Level ace (formally snap revise courses) for biology because I used their videos for the biological molecules topic and that's my strongest, I also need a way to teach myself the content so my notes are super detailed and I like videos for this (I used cognito for the whole of gcse and I want an equivalent) the only issue is the alevel ace is £72 for a year so does anyone know if it is worth it? I cant find any OCR YouTube videos that are in this amount of depth. Does anyone know another website or subscription I should get?
