thank you so much for these videos esp since there are not that many resources for ocr a biology! i wanted to ask in the playlists does it contain all of the videos needed for the ocr a level bio spec and also in the next couple of weeks would you be able to create videos for the maths part of bio and experiments in terms of exam style questions and the long 6 marker ones if you can :) once again thank you so much and hopefully can get the A in bio a level exam that is in 3 month. lastly, would you recommend for me completing all of the ocr a old and new spec past papers the ocr b ones or are the ocr b ones very different?

I’ll try and make some more, thank you for the suggestion, most of the content is there now, just the odd spec point missing. id focus on the ocr a papers but if u have done these a few times u can try ones from other specs, u just might come across content u dont need to know 👍🤞

For the last question can’t you just find the length of the scale bar in cm then divide to find how many Um 1 cm is then multiply that by how long the mitochondria is in cm

[@clarebiology2858]

yes that’s another method to do this
