Science GCSE - how much maths involved?

Double grades aren't necessarily identical. You can do differently in core and additional.

But I agree there isn't a one-size-fits-all answer. You have to try to figure out what the likely grades are, and also consider doing a third science vs another subject.

If your child is bright and ambitious, they will want to get 7 A/A* grades to give them maximum chances on UCAS. A string of Bs will not do them any favors.

I think anyone with a child in Y9 or below needs to wait and see what is going to happen with Science GCSEs. I don't think schools know yet the impact of the linear qualification. Will the 'double science' be certified separately at the end of Year 10 and Year 11? Will they have to opt into separate sciences at the start of the course and sit all exams at the end of Year 11? Will there be any scope for switching up from double or down from triple?

Do any science teachers have any insight on this?

cotton I would disagree. The disadvantage of double is that the grade is averaged. If you take triple and perform stunningly well in bio and chem but can't do the maths for physics you get AAC, for example. If you'd done the same in double you could get BB instead. I'll take the 2 As even if there's a C attached!

I think you should only do triple science if you are going to get A*s, personally.

Being able to read graphs, scattergrams, interpreting data and the like is one area of maths that appears a lot in GCSE.

There are simple calculations throughout the Physics topics. These involve substituting numbers into simple equations (which are given on the exam paper), and then solving. They can use calculators.

In Chemistry, they may have to do more complicated problem solving, but in a more limited way (ie not in virtually every topic as in Physics).

She will not be protected from calculations by doing just double science. The triple science calculations are not any harder than the double science ones.
