you have helped SO MUCH, seriously, my pregnant teacher wouldn't bother letting us write our notes or speak to us individually and she went off maternity leave recently, so most of GCSE Additional Science is about teaching ourselves and you've helped a tremendous amount in that, thank you x

[emakimberly]

Could you please do one for AQA B3
I have got my exam this Friday

Thank you so much for taking out the time to make this almost hour long revision video! This honestly helped me so much and I will go into the exam much more confident. I have always been really bad at both science and maths but thanks to you my grades have improved a lot. Thank you so much!!

[evelynmidgley]
