yeah i think crest has better value.
crests teaching is good but basing it off notes is a bit weird but their marking + qns should be good bcz unless you try hard to find econ resources you aren't going to 💀 you could make the case for notes mattering more rote learnt subjects e.g bio or...
you don't rly have a lot of choice tbh
* crest
* ace
* concept (i think they shut down though)
* private tutors
* not including project because they charge absurd amounts of $$ and no sane person would pay that amount 🤡
the closer f(x) is to 0, the larger 1/f(x) is; the x-intercept is an asymptote, the sign is maintained between them, the y intercept just gets reciprocald i think, idk what happens to the other asymptotes lol
ways to approach unique questions/steps to solve the qns rather than the formulae/unique tricks that aren't on the formula sheet e.g
\int^a_{-a}f(x)\,dx= \int^a_0 f(x)+f(-x)\,dx
(this one isn't really useful in 2u though)
or maybe some notes like how you can only do trig calculus in radians or...
yeah if you don't enjoy it that much maybe not i would put in equal effort and do math later LMAO
y11 is easier, but less interesting, y12 is harder but more interesting
just make sure you get a good teacher or something lol
