I recently came across this question, which I thoroughly enjoyed doing; "Using Fermat's Principle, prove Snell's Law." The maths involved is actually quite simple (2/3 unit level), but it's an elegant result and explains the origins of something we're expected to mindlessly apply in prelim...

I'm first in MX2 and there's a fairly big gap to second place (~10%). If I manage to keep this gap, what happens if I don't do as well as I should in my external exam? Will I get the highest mark as my internal mark and then everyone elses internals drop down to accomodate how far ahead I am...

My English half yearly is on Tuesday and I'm incredbily underprepared. I've got a creative and according to my teacher it's reasonably well written, but I feel that it's horribly cliched. As for my essay, I've done barely anything - I've got related texts and analysed them a bit + I have a...

Can someone point me in the direction of some half yearly past papers - preferably those that cover complex numbers, conics & polynomials? I've had a look in the resources section and 4unitmaths.com/angelfire and I've only been able to find past trial papers (apart from the one half yearly in...

I've got an assessment task some time during next week. We've been given a topic/area to research and then we have to do a presentation in class. The presentation involves the teachers appearing as clients seeking legal advice from us. We get given a specific scenario 5 minutes before we present...

Anybody know of any online lectures that directly address the HSC Physics syllabus - something similar to what Nigel Simmons does for maths. The reason I ask is that I'm beginning to dislike my teachers teaching style and so I need an alternative that isn't a textbook. I've used Khan Academy...

I just got myself a job tutoring (by which I mean providing help to a person that's falling behind in class - not tutoring as in "I NEED TO BE PERFECT AT EVERYTHING TO GET INTO MEDICINE AT UNSW SO I NEED TUTORING") a year 10 for maths. Two questions: 1- What can I expect? Both in regards to...

School was top 30 in 2011 Chemistry - 86 Overall Legal Studies - 80% (5-15/40)Definitely can improve this, by the end of the year I'll be at least top 10, hopefully top 5 Music - 90% (=4/7)This definitely won't drop any lower, but it might not go up either - everyone's pretty good and it's...

I've got a Physics Oral coming up and we need to submit a pro-forma with references and answer a few questions. One question is "State how you assessed the factual correctness of your gathered data" and it's worth 3 marks. I've basically said that I assessed factual correctness by assessing the...

Patel Ex 4K Q11 "The points P and Q are represented by the complex numbers z=1-3i and w=-3+4i respectively. Find a point R on the real axis such that PRQ is a right angled triangle" This is the only question I've struggled with in this exercise, so I must just be missing something really...

Just got my prelim report English 74% (82/135) Mathematics 93% (19/126) Extension 1 Mathematics 95% (5/104) Physics 87% (11/74) Legal Studies 90% (7/48) Music 1 89% (2/13) HSC Chemistry 86% (41/82) Those marks and ranks will (hopefully) go up, as I'm actually going to apply myself and study...

I go to a top 20 school that usually gets 1-2 state ranks in Chemistry each year. My overall internal mark was just shy of 80% and I'm not sure what my rank is, but I'd estimate it'd be between 20 and 30 (I did really, shit in the first half of the course, because I put 0 effort in, but then...

Chemistry rank as of half yearlies was 64/90 and my mark was 79. I've still got a prac (on monday) and trials to go, which counts for 58% of my school mark. However, I'm struggling to get good marks on essay questions, so I'm guessing my mark will drop. My school tends to do well in chemistry...
