Automatic watches beat :p

Had heaps of friends who were failing 2U, dropped to general and still fail.

Depends on which formula you use. If you use R=\frac{v^2_0sin2\theta}{g} then you wont have to. Don't remember if this is the HSC or not.

Check your sig figs rules, since your answer should have as many sig figs as the value given with the LEAST amount of sig figs. (50.0m) Hence, the answer is 115000 (3 sig figs).

They're surprisingly solid lol. From my observation, ~95% of the people will have a Macbook of some sort.

Re: 2015 permutation X2 marathon You can think of it as this way: If the player picks the door with the goat initially P(G)=\frac{1}{3} and switches, his chances of winning the goat is 100%. Since the probabilities of which of the two doors with the car behind it do NOT change and that the...

Out of the two, definitely biology.

If you fall slightly behind the published cut-off and there are any vacancies available (extremely unlikely for UNSW commerce), you might receive an offer.

If you pick electives from too many sub-disciplines you may end up delaying your graduation. That's all I can think of.

So therefore your friend is wrong if he meant you could get into medical school regardless of which uni with those exact marks.

Won't get you into USYD, UNSW though...

Total B.S. with the exception of a few courses.

They're probably gonna have relatively broad questions.

Yes

Everyone mistakes them (even uni lecturers screw up their arithmetic from time to time), practice a-lot to minimise the amount of care-less mistakes you make.

You don't have to use matrices to do the cross product. If you have vectors u=a+b+c and v=i+j+k. You can do u x v =<bk-cj,ci-ak,aj-bi> Using this to evaluate the cross product you should get u x v = 5i-4j+k.

They're a very pessimistic bunch.
