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.

Very helpful thank you so much. Would you be able to do all the hardest A* topics in a level biology that everyone finds the most difficult. That would be great. Also could you make a video explaining how you revise and your methods for success. Thanks a lot.
@BioRach
@BioRach 4 года назад
That is the aim! :) I'm going through the toughest topics first, let me know if you've got any particular topics in mind. I'm also considering making one about revision techniques and exam tips so yes, will release one at some point. 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 :)

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

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
@BioRach 3 года назад
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!
