Hi everyone, I am a 2014 HSC graduate and am offering private or small class tutoring for HSC Engineering Studies (mainly for 2016 HSC students) in the west (Parramatta/Merrylands/Fairfield area). Graduating with a mark of 96 in Engineering Studies (ranked 1st in my school) and an ATAR of...

Hey, all! If you do engineering studies, could you share your mark for it along with your internal rank and (rough) school ranking? Relatively few people do this subject and so there's not much info on marks and trends. I got a 96 for this subject, ranked 1/9 internally from a school...

My understanding is that one of the reasons modulation is needed is because: for EM waves to travel further distances they need more energy, so they need to have higher frequency (E=hf?). Is this correct? And is the following also correct?: Waves are obstructed by objects whose dimensions...

I'm having trouble finding a suitable related text for Romulus, My Father. I'm looking for a text (preferably a song or poem) that abides by this topic sentence: One’s genuine relationships with other people provide the foundation for a resolute character and consequently bridge the gap...

Can you say an experiment is 'moderately valid' as it contains features of both a valid and invalid experiment, is it only acceptable to say it is either valid or invalid? Also, can an experiment be valid but inaccurate?

My idiot cousin ran a fridge magnet along my laptop and now he screen brightness turned off and won't turn back on, even after restarting many times. Everything else works normally and the screen is still on - it's just that there's no brightness (I can see the screen by shining a flashlight on...

Hey all. I'm a year 12 student who, you could say, studies more than the average person (~4 hours a weekday). Recently I've been deprived of sleep because I can't get my mind off my studies during sleep - I'm literally doing calculations in my head or thinking of work from a certain subject. As...

https://www.unsw.edu.au/sites/default/files/documents/2014%20cuttoff%20list_ATAR_Alevel_IB_OP.pdf In some of the UNSW courses listed in the pdf above, the 'ATAR cut-off' says A+C. Can someone please tell me what that means? Thanks

how would i find the points of intersection of y=sin-1(x) and y=tan-1(x)?

Hey everyone, there's this multiple choice question from the 2005 HSC (see link below) I was working on whose answers were completely off to my answer (which I'm almost certain is correct). I got F = 3502.8 N, whereas the board of studies answer was (D) F = 1751.4 N. What do you guys think...
