DD3 has just come home from the first day of sixth form and had a bit of a wobble. She got 7/8 in combined science GCSE and is doing physics a-level but the class only has two of them who did combined rather than triple science. She is now worried she is already miles behind those who have done triple etc. May I check that kids who have done combined can still go on to achieve top grades in physics a level or is it a massive struggle/longshot for them?
