Hi there, so as someone whos actually moved sixth form for year 13, i also had really good predicated grades in year 12. I had A*AA, however in moving, i;ve had to take up year 12 and 13 classes and basically complete two years in one. IF there is no choice, then just do it, or maybe consider doing year 14, but for me i'd say that i am really struggling now because i have to basically do two years in one. I left my previous sixth form due to bad teaching so i also didnt have as much support in year 12 as i should have.Its hard work but if youre really dedicated then youll be fine. Just never underestimate how much you need to catch up on!! IF your teachers arent verbally telling you to do something you know you need to eventually do, just do it! (like research projects for non-exam/oral assessment or something)My subjects are Chinese, French and English Literature. English literature or history. things that are assessed by material like boks or time periods will be the most amount of work but it is still the best subject of my 3, so itll take most of your tme catching up on it, but if youre doing sciences or math you shouldnt have too much of a problem.
