Missed one unit of a level history

for context I moved from a level bio to history this week and have missed one unit (unit 2, maos china) - I’m super anxious as I know I’m so behind. I was wondering if other people who have taken a level history route C could answer these questions.
1) do you believe it would be possible for me to cover unit 2 over the summer?
2) do you believe I could still achieve a B or am I too far behind
3) is this a terrible idea
Thanks for a reply in advance 😜

What exam board?

Edexcel

Same exam board but I do Route G.
to break this to you but it'll probably be quite difficult as there's a lot of content especially for Paper 2 which is what Mao's China is as you need to know the period in lots of depth.

Do you believe it would be not possible to cover it over summer?
