your videos are my only hope for passing this year

[phoebel.hanson]

It would be great if you could include annotations for combined and triple, as I'd like to use this as a quick recap but I have to have my revision guide or the spec handy to tell me which parts I don't need to know.

[chingmillar]

[lucyvokes]

[elizaclouds]

Thank you so so so so so much for these videos! This is the best channel I have found for revision and my confidence for the exam (3 weeks to go) is much higher now

[elyon]

[Sarah-pcdi]

She has been very kind to provide us with help on our GCSEs and the first thing you can point out is her spelling? Do you want to pass your exams or not? You knew exactly what she meant to write, as long as you understand the video there should be no problem 😙

Guess I'm the only one cramming 1 hour before the exam ✌ living my best failed life

[jazminetalbot]

good luck to everyone doing biology exams today !

[giseleabbate]

Can the control centre also be referred to as the coordination centre? Or does the control centre involve only the brain and not the Pancreas or spinal cord? Hope that makes sense.
