That's disappointing. Thanks though.

Hi, I read that students in the HSC who achieve an ATAR of 98+ receive an offer into advanced engineering, however II just missed this mark. I am very keen on getting in, I was wondering if there was a way i could still go advanced engineering? Cheers

yes, i told my teacher i surely bombed the exam, after finding i made 5 mistakes in multiple choice. ended up with a 93

in a motor back emf increases as the motor spins faster. when back emf = supply emf, the motor spins as constant speed... and since no work is being done. it is therefore C.

16 is c, an ideal motor

Re: General Thoughts: Physics no there are no currents induced in the magnet

yes multiple choice has been tricky this year. i probably got 14 wrong then hahaha. for 19 i got the same as you, i assumed that 'low' resistance would cause minimal heating haha.

4. B: higher altitude to lower is a loss in gpe so negative? (not too sure) 11. C: law of conservation 14: B: initial change in flux is positive gradient hence induced emf is initially positive 16: C: ideal motor no energy lost hence back emf = supply for constant rate 18: C: force is given...

for 10: you know what, looking back at my MCQ paper, I did it graphically and it would've been right if I only drew in the force P horizontally. Instead I accidentally drew it in parallel to the plane, thus I had a reduced answer. Pretty sad.

8: i picked a, pretty sure you have to shade in the thread depth 10: i got c

you were right, make sure you converted kJ into J and converted km/h into m/s, sub them in and you'll get 57.5

hard to believe engineering doesn't scale any better than it does right now with a first place raw mark like that

I can only advise you to do some engineering past paper questions involving calculations. Calculations are a major part of the examination and are easy to scab marks off, even if your final answer is wrong. Make sure you can relate a question to a formula on the formula sheet on the back of...

definitely not, sorry. everyone i've seen has gotten a copy from their respective schools. if you cannot get a copy from your school today, you'll have to work off Excel Engineering or another textbook.
