i feel like there might be a hard binomial proof q13 or 14 i hope not tho

are the bos papers good? i've heard theyre really hard

what are some of the best trial past papers to do for 3u maths? (not necessarily the hardest, but a good representation of the hsc)

does anyone think this will be the year they decide to include a combinatorial argument question, i've never seen one in the hsc before

i like mcgrathematics videos he explains quite well and in a way thats interesting

i was thinking about getting an ipad for school/uni to do my work on as i feel like it'd be alot easier to manage over 29843984 different sheets of paper for different subjects. does anyone else use an ipad? if so which model would you recommend for students

what are some of the best places for hsc chem tutoring i've heard project academy or matrix are good but idk or do people recommend getting a private tutor? and do people recommend going to a tutoring centre or a private tutor for 4u math?

definitely not 75. i reckon 50s to low 60s for average

yeah i was just thinking abt that too bc the exam itself was not nearly as hard as this year, so they must’ve been pretty lenient with the scaling and marking

wait was question 9 1/4? bc all these answers are saying 1/7

praying extension 1 is easier 🙏

ohh okay thanks for that, i got worried that they wouldn’t scale both marks

WHAT so ur saying if i get a raw mark of like 75 which will scale to a 90 idk, and the person who’s mark im taking also gets a raw 75, then my final mark will be 90+75 /2

what would a raw 70-75 scale to?

i don’t get how our final marks are calculated. ik how 50% is from our performance in this test and the other half is whoever got the mark based off ur rank. do they calculate this after both marks are scaled? or do they only scale your own mark

yeahh i got that but im pretty sure its a use sec^x =1+tan^2x and just manipulate it until u get the derivative of part a and then u can sub it into the integral

i got that too

just search up "epic maths hsc" on youtube

i was i was watching ur videos earlier and ur commentary was so funny, didn't know i could laugh while watching a math video

do we have to know similarity/congruency for the triangles stuff or is that not in syllabus
