Would you go for double science or tripleWatch
You are so lucky you get the choice. I would say definitely go for triple! I was made to do double science, and it did not turn out well. My physics grade dropped my overall Biology and Chemistry grades. My college refused to let me take Biology because of physics. Ugh!
You're so lucky you get to choose what one you want to do! I didn't get to choose so I'm doing double science right now I'd strongly recommend triple science as it would be beneficial for you if you take science A-levels.
If you want to do science at A level, I'd recommend triple. It just makes things a bit easier.
Assuming you want to study something science related at further education, Sixth Forms look specifically at your Double Science results. But Triple is a nice addition as it counts as a step-up and can look good on a resume if you can get a good grade.
