I'm currently in year 11 towards the end of term 2, i know many people have started 4u maths in year 10 or 11 and others start going hardcore in the christmas holidays, just wondering what you guys did and when i should start studying to get a high mark.
depends on how much study and understanding you have for 2u and 3u
do the first half of 3u and it'll give you a taste of complex algebra
you can start with 4u any time really tho, depends on how much understanding you have for the basic stuff
e.g. for graphs its fairly easy, just know how to transform curves
polynomials requires base understanding of 3u poly
complex numbers is just pure understanding, requires understanding of base 3u poly
conics is just more complex 3u parametrics
volumes is fairly easy, just algebra and integration
integration is the hardest besides mechanics and harder 3u imo
to get a perfect understanding, what i would've done was study 2u maths in y10, touching on a bit of ext1, then start 4u mid prelim
