On a more serious note,

As long as you get the concept;

of table combinatorics (like the circle thing),
PHP such as handshake stuff (iftheres 29 ppl and everyone shook hands e.g), birthday problem etc...,
permutation/combinations questions like how many arrangements can u get from arranging SMARTYPANTS_SINGH

you'll be fine for yr 12. Its legit just grinding and knowing certain techniques. I legit just practiced these type of questions + HSC combs questions and I got those parts right in my exam, it shouldn't be too difficult
Bro that list u made was exactly what I saw in my du hw. I gave up and kmed and then just did binomial expansion which was easier somehow

Of course bro I did the course after all haha. Binom exps are refreshing after doing combs. Full 1000IQ logic -> semi 70 iq algebra brash

Let me get straight to the point, I hate perms and combs. Tbh I hate combinatorics in general. I had a test today and ngl I probably failed. This topic seems like a complete waste of time but since it's already in the syllabus, can someone give me some tips to get better? As it's going to come back in year 12 and I don't want to be completely clueless. The textbooks don't help at all, their methods/overview of the chapter makes sense, but then their questions have nothing to do with either of them.
i feel you i spent so many hours trying to understand them and getting nowhere
however i feel like it's just down to doing enough practice questions because they're all pretty similar
i found this document super helpful: https:// documents.uow.edu.au/content/groups/public/@web/@eis/@maas/documents/mm/uow168693.pdf

It's just those one or two dumb questions that have a shit load of restrictions that make it painful
