Hi, I have recently completed my GCSEs with grades 9999999988 and will be beginning my A-levels of maths, physics, FM and computer science next week. My dream is to get into Oxbridge (preferably Oxford) and study maths/physics at degree level. I have heard that it is not only about getting good grades but also doing extra-curricular activities. I was hoping to learn of some extra-curricular activities and things that I could do throughout the year, specific to what I want to pursue in order to improve my chances of getting into Oxbridge, things like specific books or videos I can read or watch around maths or physics and other things I can do throughout the year to list on my personal statement and just any general info that could help me with the Oxbridge application process. As well as this I have heard that the jump from GCSE to A-level is quite large and would greatly appreciate any info on how I can quickly adapt to this change e.g. changes in routine or just general advice for A-levels such that I can get the best possible grades I can at A-level. Thanks!
