Getting 100 is possible right? (2 Viewers)

[Giant Lobster]

From an extension 2 perspective, the ext 1 paper should have nothing tricky right? Im not really talkin from experience so correct me if im wrong, but even up to question 7, ur only enemy are silly mistakes right? or is there skillful stuff involved?
i.e. q7 usually projectile motion, binomial theorem and stuff like that, their difficulty is limited to an extent right? so hmm...

 

[Fosweb]

Many people will get 100. But thats not to say that there wont be anything 'tricky'...

 

[iambored]

it is possible to get 100%, but it's also possible in the ext2 and all other papers

 

[ND]

Silly mistakes kill of many people's chance of 100.

 

[KeypadSDM]

The chance of a 100 raw mark in the exam is (all but) infinitely greater than getting it in 4 unit. The chance of getting 100 HSC aligned mark in 3 unit is also greater. The exam's are rarely tricky, just long, and if you've got your mind around the 4 unit on monday, killing the 3 unit shouldn't be too hard.

My piece of advice is don't underestimate 3U!!! Sure, it's easier than 4U, but Q6 and Q7 of 3U, is equivilant to around Q5-Q6 of 4U...and trust me, they aren't that easy! That was my biggest mistake, my greatest incorrect assumption about the 3U paper and i did pay for it.
I would say, in terms of geeting 100, u have to work quite quickly, but also really accurately, and that is quite hard. My suggestion is to do around 15-20 past papers and practice managing ur time and making a minimal amt of silliy mistakes.
Anyways, Good Luck!

So I gather from the replies, a combination of haste and accuracy in the exam and I'll do fine? But then again that same combination goes for the ext2 paper so wouldnt fully preparing for ext2 automatically set u up for ext1?

Well when you study for ext2 wouldnt you also be studying for harder ext1 which should set you up quite nicely for the ext 1 exam.

Yes, that's exactly what i thought...but i wouldn't solely go by this. Practicing a number of 3U papers is essential and also do a lot of problems from the 3U Fitzpatrick book (ahhhh damn the bird Q!).

Is that the projectile one? Heh that one took me a while:

hehe yeah thats the one. Took me like 3 hours and finally ended up with 3 full pages of working...


and then my maths tutor did it in 5 minutes with 3 lines of working.

 

[Giant Lobster]

3 lines of working.

heh bs...

yeah that bird question had me stumped. After having gone thru 4u mechanics I'd say that question belongs in 4u

3u Fitz is good for 3u right? I wonder why 3u fitz is generally 'harder' than normal 3u, whilst 4u fitz is totally the opposite...

 

[Xayma]

That bird question is hard, maybe I should wait till we cover that in maths before attempting it.

 

[AK Gumbi]

The bird question is actually quite easy if u think about it logically (i.e if u really understand parabolas and their properties)
But doing it the projectile way, it is damn long and tedious...but nevertheless, fun!!!

I understand the way ND did it fine, but I want to wait a few months so I forget the question, then check if I can do it that way (ie I remembered the method)

properties of parabolas? projectile way?
How do you account for time then? since the trajectory is a parabola and the bird flies in a line, without time you could argue they "intersect" twice... Quite obvious. I wonder what your method was...

 

[Grey Council]

I can't wait to do this 'bird' question.

 

[skypryn]

yeah consider this - people doing 3u dont easily get 100% in 2u. there is harder 2u in 3u, but 2u is still hard enough in some places. in the same way the comparison of 4u-3u

Im not quite sure if i get u there, Lobster...?
Using projectiles, u derive all the normal eqns, and then do a number of simultaneous eqns, and substitutions, and then finally arrive at the answer (i cant remember exactly how many because i did it like 6months ago ). But my soln is quite similar to ND's soln (if i remember correctly).
But my tutor did it by using some method involving the adv props of a parabola, and frankly, i cant exactly remember it now.

I dont know abt u guys, but i always found studying a new topic in maths by myself was nearly impossible. I reckon, maths is one of those few subjects for me, in which if i dont have a teacher or tutor, im totally screwed .
