The BOS trials had many vector plane questions that required a solid understanding of the content. I've seen similar q's in trials my teacher supplied and the independent one. I'd say those are worth looking at.
Question 15 of the bored of studies trials (guided proof of normal dist) is not...
you let m be the interger solution, then equate to 4. Chuck a prime decomposition onto 4 and you get +/-(2,1) what each bracket is. Solve for m and you get your answer.
I just finished doing my trials and came across a few interesting/uncommon kinds of questions that aren't found in your standard textbook (cambridge/terry lee). An example of this would be the following:
Prove that the only integer solutions to the equation (x-a)(x-b)(x-c)(x-d) - 4 = 0 is...
is this actually true..
Edit: Not neccessarily, but OP should be wary because below avg marks + low attendance may become a catalyst to not getting their HSC. Take the advice on this board with discretion, as always.
Currently, the most efficient way to study locus problems; and the wide variety of rules/properties you may be asked to prove is to:
1. Grind out problems.
2. Identify what circle geometry property is being used.
3. Learn it and move on.
I'm still not super convinced with how thorough this...
Hey, just wanted to get some thoughts and strategies about how to (mentally) prepare yourself on the day of a 4u exam. If you found anything helpful in calming you down and letting you focus on the day of the exam, I'd love to hear about it. Thanks!
Terry Lee does not cover negation and the like. Both Fitzpatrick and Cambridge do - although Cambridge does delve into set theory and venn diagrams and stuff. Not sure about the others.

Edit: I thought that I may as well be constructive with this comment - a 3U vectors past paper would be extremely helpful to basically everyone here. Reasons for being:
1. It helps the 4U students get better at geometrical complex problems
2. A decent amount of people I interact with...
i've only just started the course so i can't really help you, but it seems you're more likely to get a response if you provide screenshots of the questions.
