Hi, I'm aiming for a 97.6+ [just a goal I made at the beginning of the year]. With these ranks and marks how is my estimate looking? School rank average: 150-200 Final Subject Ranks: - English Advanced: 10/37 - Mathematics Extension 1: 1/12 - Mathematics Extension 2: 3/3 -...

Hi, I've got a question. For the people who don't go to top 10 schools, I'm guessing the marking at their schools is more lenient in favour of them. So how does HSC marking work for chemistry? I recall the raw mark for a b6 is ~71. Do they take marks of whenever they can or what's with the...

So, to my understanding for LDPE an initator molecule (a peroxide) is required, in combination with relatively low pressure and temperatures. On the other hand HDPE, requires a zieler-natta catalyst, accomponied by high pressure and temperature. So my questions are" does LDPE require any...

I've noticed I'm quite slow at maths papers/questions. Should I attempt to go faster by rushing algebra? Is it expected that the speed of writing in a maths exam is the same as what you'd expect in an english exam? Or would you just slow it down to make less errors.

Can someone explain this to me? There are quite a lot of theories regarding how the internals are calculated. Is this one correct: 2nd person at school gets 2nd highest external mark (exam) or would it depend on the difference between 1st and 2nd and the moderation occurs from the difference...

Ok, I have some questions: 1. so the ATAR counts the people who have dropped out (prior to year 12 / HSC)? [UAC quotes it, but I've heard otherwise..] 2. is this the reason why 17% of students receive an ATAR of 90+? and the reason why the median ATAR is just 69.55 and not 50? "An ATAR...

Hi guys, I have a couple of questions to ask regarding HSC marks:- 1. I was playing with some ATAR calculators and am just curious whether it is possible to get a odd number in extension 1 maths (2 units) if extension 2 is also done? for example is 97/100 possible for 2 units of ext1 maths...

Hi guys, I have a question regarding energy bands. My teacher said they always (even at 0K) overlapped however according to the HSC sample answers they don't. Can someone explain this to me please? is this answer from Board of Studies at 0K? or at 273K? cause I believe at 273k the bands are...

How do you do this question? " Calculate the energy required to lift Peter (mass 70kg) to a location where Earth's gravitational field is negligible" I'm unsure of the radius to use in the Ep formula, it won't be zero? what would it be?

Please explain what "degree of ionisation" means, my understanding was the ability to dissociate ions (is this wrong?). What would be the answer to this question?
