Yep

Are you going to the actuarial lecture? I'm going to try make the 1:45 session

The offer is only given based off if ur year 11 marks were good enough for the course (you will be given the prep school if u dont qualify for any course). my mate got rejected from law (she got Cs and Bs at a Non gateway school) but instead got into criminology. This is more targeted towards students who have fewer opportunities, lack of funding and support. The fact u compared the average atar of 70 to a mystery mark gives it away that u clearly don't understand class/ financial differences and the whole basis of gateway being equity. Your complaint feels like a projection that u fear not getting into ur course due to a "retard" taking ur place. It's honestly a shame people believe UNSW is lowering their standards when they're actually helping disadvantaged people.

This! The reason why Gateway has changed my life is because they provide finantial support. There is no uni near me within 90km, and the lack of teachers at my school has meant that I have had basically self-study most of the year.

Same omg 1:45 we should say hiii

anyone going to unsw tmr?

yep it was cool

 

[Tony Stark]

anyone going to unsw tmr?

YESS I WANNA GO SO BAD IMA WORK MY ASS OFF TO GET INTO UNSW

 

[bigupsanky]

guys how to do binomial proofs its so weird i dont get it.

 

[Study to success]

it's 6 7 weekend

just gotta expand yk

 

[Study to success]

Guys what should I get for lunch after my Eng exam on mon

 

[bigupsanky]

just gotta expand yk

nah like prove 2n c n = so and so

 

[Socialism]

67 or 41

 

[alphxreturns]

nah like prove 2n c n = so and so

the 'given (1+x)^2n = (1+x)^n (1+x)^n'?

look for coefficients, look for substitutions for x, look for anything thats recognisable from either lhs or rhs. like derivatives or integrals

 

[bigupsanky]

like this maybe?

 

[melanie_o]

I'M SO SCARED? LIKE ALL MY TEACHERS ARE PREDICTING 2025 WILL BE HARD THIS YEAR. LOL 🥲

Hard as in hard exams????

like this maybe?

(1+X)^(2n+1) = (1+X)(1+X)^2n

expanding LHS

(2n+1)C0 × X^0 + (2n+1)C1 × X^1 + ... + (2n+1)Cn × X^n + ... + (2n+1)C(2n+1) × X^2n+1

symmetry of Pascal's triangle means nC0 = nCn
and so on, (2n+1)C0 = (2n+1)C(2n+1)

so since 2n+1 is odd, (sub n = any number if u want proof)
letting X = 1,
the expansion is 2((2n+1)C0 + ... + (2n+1)Cn)
rhs = (1+1)(1+1)^2n

so 2n+1C0 +...+ 2n+1Cn = 4^n

sorry I'm pressed on time but the main part was symmetry and X=1

Hey, is early entry for UTS closing today at 11:59pm (7th September) or tomorrow at 11:59pm (8th September)?
Thanks

oh ye u right ty ty

Maybe try studocu.

I didd but I cant find any
