Please stay on topic ppl

Look up the Maths Ext2 BoS trials. A lot of the old syllabus questions on resisted motion and projectile motion are applicable in the current syllabus as well.

Just a remark. Generally speaking, definite integrals where one of the points is undefined (x = 0 in this case) does not really appear in the HSC exam itself - if it ever does then they make it very clear you are taking the limiting value rather than evaluating it at that undefined end point.

Hint: Split the definite integral of ln(sin 2x)

Please stop derailing the thread ppl…

Not sure what you're trying to do, but the goal is to find the value of t such that P = 0. dP/dt is the rate of change of the population. The population itself is represented by P. You need to find the solution to the differential equation to P in terms of t. After that you can them solve for t...

Actuarial studies is very data and application-centric and not really the same as solving pure maths problems like you would in Ext2 Maths. Think probability, statistics and financial maths on steroids. It’s about coming up with models to estimate or measure something that is uncertain. If that...

Nice to have with luxury of time, but this should never be at the expense of learning the actual syllabus content. Anyway, all HSC questions should be doable using syllabus content only (what makes them hard is knowing how to apply syllabus content in unfamiliar contexts), and anything beyond is...

There’s reason why median ATARs are reported by schools rather than mean ATARs…

FYI the 2022 Maths Ext2 HSC had a question that was almost identical to one in the 2005 Maths Ext2 HSC. Just sayin…

You will usually be expected to derive the AM-GM results from scratch. Either way, the HSC questions will make that very clear. The only real mention of AM-GM is as an example of an inequality in the syllabus and even then it is framed as a derivation (with the word "establish") for two...

It was great to meet the people behind the usernames! If this is something people are keen on, then happy to organise another event next year. :)

Looks like Ruse didn’t have a great year from a band 6 percentage basis. They typically hit 70% or above but are at 67.7% this year (followed by NSB at 62.8%). Very surprised Sydney Boys and Sydney Girls are outside the top 10.

First in course list will be posted in this link: https://educationstandards.nsw.edu.au/wps/portal/nesa/about/events/merit-lists/first-in-course/2022 but if you can’t wait then see https://www.smh.com.au/national/nsw/the-state-s-top-hsc-students-in-every-course-revealed-20221208-p5c4wn.html

The UAC calculator uses actual historical scaling data which is something the private company run ATAR calculators don't have access to. However, that still doesn't guarantee it is 100% accurate, because the exact scaling differs from year to year.

Bump!

Location is being decided within the private convo discussion, for those who are serious about attending

Bump! If you wish to attend the BoS meet up on the 18th, please post here and/or send me a PM
