It's not to difficult- I think the biggest difficulty is staying away from rote learning and actually making sure you understand concepts. At my school people got smashed in the first test because they tried to rote learn and didn't actually understand the content...
I want to self-learn the differentiation/calculus content for year 11- which textbook/resources are best to use and are there any tips/tricks that would help. Thanks in advance.
That amount of time is absurd. A close friend of mine did the hsc last year and got 97 in advanced without reading texts- he spent awhile perfecting creative and essay and that was it.
