Math Advanced Prediction/Thoughts (3 Viewers)

Well I’ll take your guys word for it, but I do find it difficult to believe you needed to be an extension 1 student to not be rattled by the exam.

ye bro, a few 3u kids struggled in that test

im gonna drop a scorching hot take rn. the advanced exam wasnt even that hard
ill explain myself.
q 11 - 15 were free. 16 is a bit hard because of the quadratic inequality, 17-26 were steals, but some may have lost marks at 26b, 27 i really liked because its physicsy but the principle is still there, not the worst, 28 may have been hard to visualise to some but still simple if you knew translations. 29 is decent but part b is hard, you need a minute for that but i reckon it would be easier if you studied similar questions in annuities, 30 is weirdly worded but doable, 31 is easy, 32 onwards was moderate

in exam conditions, it was ngl

i mean given there is common content majority of b1-3 questions are gone from that (my prediction) so thats why so many b5-6

thats true looking back 4u wasnt as hard as i thought but in the moment i was in panic mode for some questions i shoudlve gotten

it was just unexpected to have so much probability...like i didnt study THAT much for it coz i expected the usual

the only notable and pure probablity was the last iq part which required conditional. other than the only probability was normal distributions

yea that was disgusting

 

[DarkOperator618]

whatever tho, we gave it absolutely everything

no point stressing about the results now

 

[stupidpersonlol]

lets move on everyone x

I'm not sure if people will agree with me here or not, but I'd say probability is probably the hardest topic in 2U; not because of the content or difficulty, but just because of how obscure and technical it can get.

its just logic tho...

what if u dont have logic..

 

[icycledough]

not sure what u mean by 'obscure' and 'technical'

I think I didn't phrase it the right way, but what I should have said is that with topics like differentiation and integration, at a 2U level, there is a set way (using the rules of course) to go about any given problem. With probability, I just found it quite difficult to grasp all the concepts and formulas which will be needed. I guess some people will love statistics, but that was just my 2 cents on it.

What is meant is the amount of detail involved such as cumulative distribution function and the fact that one has to pay so much attention to detail in the question to not even get a step wrong. Obsecure is because one might think they have an answer and go what I am going nowhere and as such must readjust which can be difficult for those of us who went very deep into one way of working.

I think that's exactly the way I was trying to word my response but I just couldn't put the words together like that.

have they ever asked a question about a cdf using the fact its always monotonically increasing (i think)

 

[DarkOperator618]

we r gonna have to live with shitty headlines like this for the next week or so lmaooo

the media have taken it out of our hands

i really don't like this aladeen portrayal of hsc exams by the media tbh

 

[Trebla]

It’s still early days of the new syllabus but here is a nice question (technically Ext1 level though) which uses that property of a cdf

Let X be any continuous random variable with a cdf of F(x). Let Y = F(X). Show that the pdf of Y is that of a uniform distribution over [0,1].

this is in the bos 2020 trial isnt it. i actually had no idea how to approach this but the answer made so much sense i really like it.
