A lot will depend on your subjects and out of the subjects you chose I only took English. I always brought pens and highlighters, I had one pencil I never used and I brought lined paper and a plastic popper file to store paper from the week to transfer home to large ring binders. Amount of revision is entirely subjective, don’t work a certain amount of hours work what you need aka revise enough to pass class tests and understand content and finish any homework set. I used paper because I can’t revise off a screen and so always have to print a load of stuff off it depends who you are, loads of people brought laptops and had online notes but I’m not technological. Sometimes teachers may want essays for English I typed those and brought them in. I also managed to accidentally merge my laptop files with my phone don’t know how I did it I was trying to do something unrelated but it was useful if you can do it. I wasn’t new to my sixth form as it was my same school but I don’t think you’ll have a problem as everyone is really open to new people and the new people who joined my school slipped in to existing groups easily. My friends for example gained two people. English specific tip that changed my English revision highlight key quotes in text as you are going along bookmark them with a sticky tab so it’s easier to make quote cards for revision. Don’t stress about free periods to much in year 12 use them when you need but also take a break if you can and want. The only time I worked flat out was the last two terms of year 13 (after Xmas) and a few weeks before my two AS subjects as this was revision. Now AS exams are gone I see no reason to work too much in Year 12 but it’s all personal. I also want to say though don’t worry about starting year 12 too much you’ll learn methods and routines that suit you very quickly, the opening weeks are all about getting used to your subjects and teachers and the school as you’re new anyway so you’ll have time to adjust. I’ve just left year 13 and looking back the jump wasn’t as bad as it had looked before I started but then hindsight can be a bad premise to make assumptions from.
