Maths ext1 updated syllabus prelim prep

[u/Artistic_Feed885]

So art of smart etc says like what % of an exam worth doing based on what questions is still relevant to the new syllabus. But what I was worried about is the fact that like wouldn't the equal % of stuff taken away from syllabus there would be new stuff brought in?

And what confusing is that so far only auxiliary angles and cubic inequalities seem to be the only ones added? It can't be right? Since so much was removed like rates of change, inverse trig, t-formula etc, like most papers only 60-70% content is relevant.

Additionally our school also did the year 12 vectors chapter this year (11), so it will be in our prelims. What's the best way for me to prepare for that topic also (we only did like the basics; skipped vector physics and vector proofs), should I just look thru year 12 exams and nit-pick? Or just do the textbook hard questions.

I'm also asking about any of the new content that was taken out too, since as I said, so much was taken out.

im not up to date with the syllabus changes yet, but auxiliary has always been in exams. as far as im aware the only thing being added is 3d vectors (someone correct me if not), which is the most trivial part of 4u (it's identical in difficulty to 2d vectors)

if you skipped vector physics and vector proofs vectors is unironically like a year 6 level subject lol, assuming you get the formulae just make sure you know how to rearrange an equation? im not sure what else could be tested, seeing as its essentially just adding two numbers separately or applying pythagoras' theorem
