This video helped my son get an extra 16 marks between past papers taken yesterday and today!!! Thank you . We you be doing the same for chemistry and physics paper 2?

[hollie]

thank you so much for these videos- seriously saving so many of us

[bxr]

will you release the chemistry and physics versions before the holidays are over or just before the exams?

[M]

Primrose could you please do an updated Biology Paper 2 Edexcel Prediction

[Ehhyw]

Can you please do this for physics as well?❤❤

[rockondude]

as you said on the description that the whole topic video do not cover everything - what else should i do to cover the rest - for now i will be making notes then doing past paper, any suggestions

[XXXXXX-uynu]

May be a silly question but does this cover the triple only content as normally it says in the timestamp but before i watch the video just wanted to make sure that it covered the triple only and if not will you be making a video doing so?

[hhsisisis]

[fallthrone]
