Maths Extension 2 Predictions/Thoughts (2 Viewers)

[lawfirm]

does anybody know if our ext 2 response papers are scanned or marked physically? My teacher told me that they marked them physically and therefore I could use an erasable pen however I just want to confirm this as it would suck to have all my answers melted away.

don't use an erasable pen in either circumstance because they can fade from the heat of being transported as well as not showing up in scans. some schools ban them on all tests for this reason, as well as appeals ofc for school based

 

[lawfirm]

uhhhh you've been lied to sorry, they get scanned, that's why i always go over pencil diagrams in pen

I think pencil is ok because NESA specifics you can use (but only) a 2B pencil. still better be safe then sorry

the scanner is prolly 50 degrees, ur ink will disappear lol

and this is another reason it's unfair, unless your teacher has marked they have no idea how any of this shit works because its some state secret

omgg so scared for tmr like i also hope its not too bad... trying to e4 would be like getting a raw of 70+ but I CANT DO QUESTION 16s - like they're so different every year too idk how to prepare for it ;-;

even if you fail q16, there's till like 15 marks to play with before you get below 70

You literally can get a complete 0 and still e4- ur fine

What raw is everyone aiming for? Hopefully i can pull a 72+

they're kinda only done by 140+ IQ ppl

hopefully raw 80

Whatever gets me an e4 so prolly like 70ish

"Childcare" is quite sus

coefficient of friction isn't in the syllabus right?

coefficient of friction isn't in the syllabus right?

I don't think It's directly addressed in the syllabus but I've seen a lot of questions which include it as another resistive force, typically on inclined plane questions.

hopefully raw 70. i think my internal mark is like 92-91 ish rlly hoping to get like a 90 external but worried how hard they're gonna make it and i hate the questions where there is like a tiny little trick (probs most of them)

anyone think they're gonna do like the integration proofs like the ones with the rectangles above and below the area of the curve

Pretty likely. They have not had such a proof in the HSC for many years

wait what do you mean by rectangles above and below (uh oh)

 

[bigbird102]

we had a 4 marker on it in our trial. U can see one on James Ruse 2020. Basically it just involves sums and algebraic manipulation. The main thing to know is the rectangle below the curve<Area under the curve<Upper rectangle. Probs doesn't make sense but look at James Ruse 2020. I'm a bit suspicious it will pop up cause im yet to see it in a hsc paper at least recently

coefficient of friction isn't in the syllabus right?

Friction coefficient IS in the syllabus, hidden in the glossary section. Just remember its a constant times the normal force and the normal isn't always only just gravity but can be caused by any force directed partially into the plane (hence creating a reaction force)

 

[bigbird102]

does anyone just any like tricks for proofs. for example just quick stuff like odd-even=odd. like ik its obvious but any like common proof tricks as there niche at times
