Hey these are very good videos, thank you for making them. Could you possibly put the new videos into the playlists, I dont know if the playlists are up to date or not, this will be very helpful if you could do this. Thank you.

[@BioRach]

They should all be in the right playlists but I'll double-check :) Glad the videos helped you, thanks for watching!

Hi, love your videos. In the specification it mentions Purkyne fibres but not Purkinje fibres. Would I still get the mark? Thank you :)

[@uaimen3990]

Yeah you should because they mean and are the same thing, just different spelling 👍🏼

[@BioRach]

Yes exactly :D I get confused with the spelling sometimes too, but it's just the British and American spelling thing...

[@ryankirk4965]

Thank you so much, this was so helpful. Could you please add more videos in this chapter as I find it one the hardest topics

[@BioRach]

Will do! The aim is to make videos to cover the whole spec :)

[@nourmoutaz7968]

can you please do a video of electrocardiograms? :))

[@umairaosman2652]

your videos are soo helpful, thank you very much :D

[@meowmeow-dw3bi]

amazing :) never fails to disappoint

[@multazammohsin838]

would've been even better if you'd cover electrocardiograms

[@theosymons4891]

Thank you!

[@maheknadeem1193]

This video was really helpful! I’m not sure if you’ll see this comment but I just wanted to know in the exam are you allowed to use the abbreviations in your answers so instead of saying atrioventricular node you could say AVN instead. I know that this is the case for the DNA topic (mRNA, rRNA etc)

[@BioRach]

Glad you find it helpful :) some common abbreviations are allowed in exam, like the ones you've listed (I *think* AVN is acceptable). But just to be safe, I'd suggest you write it out in full, then follow with the abbreviation in brackets, after that the abbreviation would be fine - this is especially the case for longer responses. Just remember that different examiners will mark different questions from your paper, so if you've written the full name and abbreviation in Q1, it may not be seen by the examiner marking Q2. Hope this makes sense!
