I'm finishing year 11 now and I'm having a lot of people tell me different stuff, some saying I should just chill and make the most of my summer until sixth form, some saying I should get started on A-Level content now, and some saying I should start working on my supercurricular activities. Any advice? Would it even be worth it to get a head start on A-Level content and/or supercurriculars for my personal statement?
