Heya, I’m in year 12 now and I take maths, further maths, physics and economics. My college does it so that you take all four subjects over the two years and with further maths, maths has seemed really easy so far, basically only covering higher level GCSE content, so if you’re predicted 9s I don’t think you should struggle. Further maths has been challenging sometimes, but it does feel the most rewarding out of all of mine. Physics is also very maths based, for my exam board there’s a surprising amount of trig so far, so I think your options would be really good!
