It's interesting how the HSC exam specifications state that at least two sub-questions in chem will be worth 7-9 marks although a lot of the school trial papers don't include huge questions/split them into bite-sized pieces. Maybe not so common in chem since an integrated spectra question can...

Generally, the new syllabus science subjects have been explicitly trying to steer away from theory dumps, Chem has also been that way for the past two years too; it's an efficient way to throw curveball questions while remaining within the scope of the syllabus

they could maybe make it a data-processing type of question where you could evaluate the method of a given experiment or why the results are the way they are, but other than that I don't think they can really ask a huge malus' law question; it's not exactly famous for its variation after all

i really hope module 8.5 isn't gonna do us dirty this year that being said I'm also curious to see what the 7-9 markers this year are gonna be on

module 3 in year 11. used for prelims, and used to be in year 12 in the old syllabus. we don't really need it unless they explicitly test redox reactions which is probably not going to happen

i'd prob be fine with any as long as it's not the extensive ion testing stuff lol

the new syllabus is definitely leaning more towards calculations and data processing so I think that'll be fulfilled :D

It's helpful to keep in mind for why we can approximate sample proportions to normal distributions under certain conditions, but we don't need to know about it.

Advanced is assumed knowledge so technically you should know about it, but since Extension 1 has almost the same amount of content to cover with 30 less marks in the exam, I doubt they would do that That being said, continuous random variables mostly just involves integrating a pdf function...

I think they can test some trig transformations (auxiliary angle) and real life problems which is sometimes done in SHM but you don't need to know anything about its motion equations e.g. rising tides with a given trig equation

i just kinda hope there isn't too much focus on combinatorial proofs, since the syllabus is really unclear about what they can ask on it ahaha

it has its own name because it's most frequently used for population modelling as opposed to the other equations which can be applied to other systems such as cooling. there's a chance they might since there's a dotpoint in the syllabus to model diff equations in different contexts including...

pretty unlikely that they're gonna, there's already 7 topics to be tested in 70 marks so I'll be surprised if they have spare marks for random 2u stuff hmm. tho I'd probably prep some of the advanced stats stuff like continuous variables bc I think my school tested a cdf question in one of our...

yeah, probably expecting more vectors and stats this year, considering only 3 marks of the 70 last year were taken up by a very dodgy stats question and the absence of proj motion

Oh my god ahaha i changed my answer from d to c since i interpreted it as saying that the speed of the vector was increasing and it had to remain at constant speed in order for UCM to occur rip

god when i saw one question take up an entire page, that scared me. at least during reading time.

they're referencing whether a cdf should be written with three parts, as there's a section for when the cdf is 0, and then the next section is the result that you get from integrating the pdf, and the third section is 1 (after all datapoints have been taken care of within the pdf), and yeah it's...

I think we get some booklets to write on with question numbers (tho with 4u we'll probably need extra booklets). I'm looking forward to losing the order of them tomorrow :(

I'm a bit worried about MCQ for some reason lol they always seem to touch on some pretty niche points or throw some mean looking scenarios especially in the more recent exams

yeah it's really weird, although nesa classified it as being a 'nature of proof question'. nesa's sneaky 3u is assumed knowledge so they can probably combine whatever topic they like and still have it considered as a "4u question"
