I'd recommend first carefully going through anything that you don't understand or feel confident with and reading your textbook/watching videos before trying as many questions as you can on the topic.
Then you could try revising in the same way as you revised for your mocks and give an AS past paper a go and see what grade you get. If you're still at a B then try again.
Year 2 builds heavily on year 1 so I'd recommend aiming for an A standard before moving on to year 2, especially if you want to do maths at uni.
