we normally have seven periods a day, each 40 minutes. you'll be in school from 9 to around 4 ish, apart from saturdays which end at 1 and sport can end at 3 if you choose the right one. i've heard that some teachers suggest you stay as late as 6 but that's not really feasible, especially when so many of us live quite far from the school. you'll have four frees a week and lunch is quite long, ranging from an hour to an hour twenty i believe.
teachers are generally good, i don't have any bad ones fortunately. they're all willing to help you if you have a problem, even if they don't teach you. most are strict but firm, like if you're constantly not giving in homework you will be reprimanded but you're also praised for good work.
lab is a time after lunch for about an hour and a half where we have private study. it's different to a free in the sense that you're supposed to be 'scholarly' (if you come here you'll hear the word a lot), by getting help from a teacher, doing wider reading or group work. it's not meant for doing homework, but most people use it for that lol. cultural perspectives are like a type of enrichment, they're extra classes that you choose at the start of each term and range from debating ethical dilemmas to learning an extra language (mandarin, italian and french were options this time around). it's a good opportunity to learn about things you find interesting but didn't want to do a whole a level in (i do two philosophy based cultural perspectives) and you have three a week. the downside (for me anyway) is that you have to do a response at the end, meaning you have to take what you've learned throughout and respond to that, usually in some sort of extended writing
entrance exams were a bit meh, i was worried for them going into it but the time flies by (for better or for worse). i did mine in maths and french. maths was fairly standard, nothing you won't have seen in gcse (algebra, probability, shape stuff). french was a lot harder, we had to translate a couple of sentences, do a reading comprehension and a mini essay. i remember feeling glad that the maths had gone so well because that's definitely what got me an interview haha
what subjects are you thinking of taking? and it's fine, ask more questions if you want
apologies for the long reply also
