if you are worried about the workload that advanced math brings I guarantee you that that extra workload is negligible in comparison to the work load needed to do well in physics alone.

it does not matter what mark they got internally given that they came first internally.

no its not dependent on internal mark, as i presume OPs friend is rank 1 internally meaning they will get their external mark for their internals, given they come first externally aswell.

it is important that its less than 2.5, because the question states that 'the sample size is chosen so that the chance of shutting down the machine unnecessarily is less than 2.5%'. So this means since you use z=2, the upper 2.5% will never cause the machine to shut down because it is at the...

I got C as my answer and what i did was: emf=(0.03 X 0.05) X (100) X (0.35) X ((cos(55)-cos(90)/0.33) = 91 mV

your friend shouldn't be expecting a state rank if they aren't certain they are on 100 raw, given that many students who get 100 raw do not get a state rank in 3U.

hoping for a 9 marker on validity of experiments.

yes but unlikely for maths

the wording of the sample size question was so long that i didnt see 'round to the nearest thousand', gonna lose a mark to not rounding imagine that.

I think its a good system as it is quite neutral in its use, as throughout the year students have worked hard to attain their internal mark and if it is just unraveled in the externals it is quite unfair. So the top ranks taking the higher marks makes sense in that aspect, however, with the lack...

So for your external mark, you will get the mark that you got in the actual exam. But for internals, you will get the mark of the person who placed your rank externally, so if your rank is rank 2, and the second highest exam mark from your school was a 95, you will get a 95 internally. So doing...

that should be right

yeah i feel with new syllabus they wont include as much conventional locus questions and it may be more need to be thought of more intuitively rather than algebraically.

isnt z=-pi out of the principle argument domain

ive lost like 12 marks definite, probs aiming for like 85ish. I hope scaling is like 2013.

what do you guys thing 84 will scale to

wasnt too difficult, it will a bit harder than last yr. I think ppl arent used to the question formats

what do you guys reckon the raw mark for a 97 is gonna be this yr?

it shouldnt matter too much as the main part of the question wasnt to refer to the extract (it was like that for my text).

you can refer to them only, but i think it is stronger to use the extract once or twice to reinforce your point
