thank you so much. i’ve got chemistry paper 2 tomorrow and this is the last time i’ll be doing chemistry! your videos have been so helpful and the visual method of teaching is really helpful. i’m hoping to get a 9-9 in combined science as i got a 8-8 in my mocks with your videos :)

I went from grade 3 to grade 8 in chemistry because of your videos (and obviously exam questions ) so thank you so much :*)
