Hey there, I'm in year 12 studying the three sciences and maths for A-levels. I've agreed to take part in the BBO this month (aimed at year 13, but put forward by my teacher) and even though I've looked over some of the more advanced content and looked at the sample paper, I'm still unsure about how to approach it. Does anyone have any gems of advice they can give me? Any constructive advice is much appreciated!
