Giving notes to teacher (sixth form)

I think redundant because many other people probably have written the same notes as you, it’s just people apply it differently in exams which is why same text book but different grades

Maybe not sending them to the teacher, but if you know any students in the year below ask them if they want the notes? I know personally that as a lower sixth I much preferred writing my own notes and then comparing them against other peoples notes or online notes etc. So to some of them it might be really helpful.
If you don't know the first years yourself, then perhaps talk to the teacher and discuss whether they'd be able to put the notes somewhere where they are available to the first years. A Google Classroom or something.

what if i’ve basically collated past paper stuff, and different resources all in one lot? just wanna help ppl in the year below but idk

Gutted that I wouldn't be able to sit alevels this year - although I know there are other exam arrangements, it's unlikely I'll sit them.

I've put so much bloody effort in my notes and it feels like it's going to waste. I'd really like to give my digital notes to a teacher I really like + I'm one of the top students in the cohort (not trying to brag, just thought it might be informative). If I email him the notes in the summer do you think he'll appreciate it? Or will he just think they're redundant

planning uni?

wdym?? haha sorry didn’t really catch that

To be honest, it would probably be better to apply those notes to i.e. writing timed essays - you could then send to these to your teacher as evidence of your work when under exam(ish) conditions. You could always offer to send the notes to the year below, though this would probably not be worth doing as I expect they'll be making their notes and revision resources.
