Thoughts on the paper? Any questions you liked or didn't like?

 

[BLIT2014]

I haven't seen it but I thought it had lots of maths in it.

 

[Tofite]

Paper was largely fine until question 14. The infinite series question was quite difficult but was able to be done with some manipulation of the final result. Definitely more difficult than 2017 again, same as 4U.

what did u guys get for 10? I thought it was A but it was done haphazardly

What was Question 10?? I think I guessed C.

I guessed D but apparently its B

 

[DrMoller]

DID ANYONE GET THE LAST QUESTION AND NOT GET THE BISECTING GEMOTRY QUESTION???.


That was me... I need someone to relate to please....

 

[MinaSaw]

Someone upload the paper pleaseeeeee

I put B. I did it by getting it into a square, put it into normal form, find a and centre, then it’s just the sin function cuz starts at centre. Hopefully I’m right.

I managed to get most of the last question
That paper was definitely much harder than 2017. Expecting e4 cutoff to be less

I'm looking at about 60+/70 raw, seriously messed up inverse and then the last q ~ So fucking pissed tbh

Paper was easy for me until the 4 marker, which I barely managed to get in the last few minutes.

Weirdly enough I couldn’t get the result in the preceding 1 mark question even though I checked my similar triangles 5 times.

Probably made a few sillies elsewhere.

Was the exam out of 70? I didn’t notice what it said on the front.

solutions from NGO and SUNS didn't show that |r| < 1 for 4 marker at the end. I think they would lose a mark

 

[concordhs]

messed up the inverse function q, didnt see the x>1 part so 3 marks gone

Probably. But I guess we can cut them some slack since they got it out so quickly.

I'm still plodding along slowly but I've made sure to explain everything in detail.

I made a fair few stupid errors and feel like an idiot
- Didn't do the proper inequality method for 1e
- Didn't restrict the domain for the inverse, didn't see the 'at least' in the probability
- was trying to do Pythagoras to find ST, for some reason didn't use the distance formula directly ffs
- missed the last part of the induction
- screwed majority of 14 up

I reckon just over 50/70 raw.

 

[sourish]

would anyone say that this paper was harder than the 2009 paper?

 

[123qqxxzz]

AHHHHHHHHH sillies (, forgot to conclude with f^-1(x) = ... and left it as y= .. and woo minus signs :'(

Thats what i reckon i got as well. I made the same stuffed up the inequality and I didn't have time to attempt much for question 14.

 

[jjuunnee]

yeah i found this a lot harder than past papers but also that might be bc my brain was like dying halfway through hahaha
hopefully i didnt make too many silly mistakes or else there goes band 6 lol

 

[Lolihentai]

ahh same misread the 'at least' in the probability section. fucking rip. and messed up bits of q14 throughout
