Yea naaaa m8 haha, highly unlikely they wontso there has always been a projectile motion question every year (i think), maybe nesa won't put one this year to troll us?

Also, does the state actually do bad in projectiles??? 3u projectile don’t seem too bad, I thought the state struggled more with circle geo tbh. Projectiles is usually just algebraWishful thinking, but it's highly unlikely. NESA most likely does that because the state usually performs quite poorly in Projectile Questions (or at least the later parts of the problems).
Tbh I don't think its the algebra, the difficult part of projectile is understanding the question !Also, does the state actually do bad in projectiles??? 3u projectile don’t seem too bad, I thought the state struggled more with circle geo tbh. Projectiles is usually just algebra
For question 11e i dont understand why you multiplied the answer by 6 (ik the answer says "because there are 6 different colours that the dice could land on"), but the question only mentions the probablity of the same scores, why do the colours effect the final outcome?LaTeX solutions, until q12 something. I didn't finish coding it, sorry, bit busy with HSC. EDIT: my dumbass also in a haste messed up q2 mcq, the answer should be 2/a I think from memory
I would imagine so, I mean it is towards the end of the paper and people would come across it with say 20 mins left and get frustrated because they don't know how to proceed e.g. the results involving the inequality signs.Also, does the state actually do bad in projectiles??? 3u projectile don’t seem too bad, I thought the state struggled more with circle geo tbh.

Because the same scores can occur for the 6 different colours, and otherwise we are only considering the probability of it happening for one specific colourFor question 11e i dont understand why you multiplied the answer by 6 (ik the answer says "because there are 6 different colours that the dice could land on"), but the question only mentions the probablity of the same scores, why do the colours effect the final outcome?
From all the “notes from the marking centre” docs I’ve seen, students seemed to struggle most with geometry in general, apparently e4 students even struggled with proving the 1 or 2 mark similar triangle question last year!I would imagine so, I mean it is towards the end of the paper and people would come across it with say 20 mins left and get frustrated because they don't know how to proceed e.g. the results involving the inequality signs.
Feel free to look at statistics and tell us what you find, most of 3U Circle Geometry is usually something relating to the alternate segment theorem or proving that something is a cyclic quadrilateral - not exactly difficult stuff...
I think it's a poorly worded question, Skuxxgolfer is assuming the dice are all different colours not the faces of the dice.Because the same scores can occur for the 6 different colours, and otherwise we are only considering the probability of it happening for one specific colour

Ohhhhhhhhhhhhhhh, okay i get it now tyI think it's a poorly worded question, Skuxxgolfer is assuming the dice are all different colours not the faces of the dice.
Yep, that was off 2018 independent 4u trials.I think it's a poorly worded question, Skuxxgolfer is assuming the dice are all different colours not the faces of the dice.
Can confirm I did not struggle with this. Took me about 10 seconds.apparently e4 students even struggled with proving the 1 or 2 mark similar triangle question last year!
Ikr, I found it weird. Either NESA is lenient on e4 cut offs or our mathematicians do not like basic geometryCan confirm I did not struggle with this. Took me about 10 seconds.
Not really, NESA does it because the HSC exam is meant to cover all key topics across the syllabus. It would make no sense for them to suddenly skip an entire topic in the HSC exam.Wishful thinking, but it's highly unlikely.

Yeah that's something I completely skipped over ngl.Not really, NESA does it because the HSC exam is meant to cover all key topics across the syllabus. It would make no sense for them to suddenly skip an entire topic in the HSC exam.
Mhhhm interesting point, I agree !I have an uneasy feeling the last question this time might be a functions and inverse functions questions. It’s been a while since they did that (14 years, 2005 iirc).
When I did the binomial question (2018 hsc) I got it out by firstly writing out what term each coefficient is representing. Like for example every second term was of the formAnyone have like last minute tips for those proving binomial identities questions? Or is it just one of those topics where you either see it or you don't?
If it helps, the ones I specifically struggled with was 2013 Q14bii) and the one with the grid question (can't remember)
