4u maths VERSUS 3u maths (1 Viewer)

[VanCarBus]

I think that 3 unit maths is like formulas and thatz it. you don't need to know anything. Everything is like there for you. All the answers are in the question.

With 4 unit maths however, you like havta jump around, do something weird and then you get 1% of the answer. Mix more lagebra together until you finally get the solution. You cannot check your 4 unit work properly, where in 3 unit maths, u can work backwards to do so.

4 unit maths is like an entirely different course than 3 unit maths. 3 unit maths is more like 2 unit maths.

Yeh i agree that 4u is in another league (well maybe q7 is comparable), but what do you mean when you say you can't check your 4u solutions?

 

[Jumbo Cactuar]

yes I find I teabag 3U cause I have had experienced pretty much every question they can ask, but with 4U there endless permutations of the type questions they can ask. You go into the exam with your skills and hope you can see a way through to an answer (not nessessarily the right one half the time!)

 

[turtle_2468]

I'd agree, except for the checking answers bit. I find that I actually tended to make more silly mistakes in 3U, because in 4U a lot of the questions are of the type "prove that blah is equal to blah (insert algebra here), which means that you HAVE to get it right to get the required formula (unless you fudge it!) But in 3U, there are all those "calculate htis integral" or "approximate this" calculations, and those you really can't check except by going through all the working and hoping you didn't press a button wrong somewhere...

hey, turtle which calculator did you use?

what a silly question, it's turtle we're talking about here......he doesn't use a calculator!

 

[underthesun]

He uses one of those in-built ones special for human craniums, much like the T-100 and the T-X. Those probably allowed him to check the exam twice!

by the way, I heard some high schools got an advantage because of using graphic capable calculators last year. It was an allowed calculator, and I think one of the questions in 3unit was made much much easier with those calculator. At least that's what I heard from some teachers...

following that line, I heard they allowed one calculator which does definite integrals

*goes on to the search of the ultimate HSC calculator*

but dang, i'm already too used to this one i have, plus you'll probably have to derive it without calculator anyways..

Is the extra 1 minute you save in the exam worth all the $$ and time spent learning to use a new calculator? \

side note: Casio fx-100s rocks.

 

[underthesun]

Probably. That's 1 minute out of total 180, so proportionally you should be spending 180 more times learning how to use a new calculator

btw i'm bringing 2 calculators, maybe more if I get to get a good one. Shopping time soon~

 

[ND]

Yeh i'm gonna bring 2 or 3. Mine crapped out midway through my first 3u assessment, luckily my teacher let me use his (even though i had nfi with it).

That's not an issue

To be a good calculatorist, you should not know which keys to punch before the calculation and not remember what you've press afterwards.

You still have to learn how to use memory and stuff though. I use memory alot. And you don't want to be sitting there looking for pi or nCr or something during the exam.

*sigh*
i broke mine a couple weeks before trials, they dont make that model anymore

i don't think that u'll b allowed, coz u can only use calculators list on the following site:

Okay, 3U is good. Most of the work follows straight on from the 2U stuff (except evil binomial theorem... grrrr), and it is possible for me to understand the concepts.

4U is bad. Most of the work is detached from 2U and 3U. It has slowly driven me insane over the last year, and its only in the last few months that things have started to make click for me. But on the plus side, it makes you really appreciate 3U.

And you can scare 2U and 3U people by yelling 'the square root of -1 exists!'


And as for calculators, the Board of Studies are evil for not allowing them in the Software D&D exam.

so which one was it?

*thinks about taking two calculators into the exam*

You really should be taking more than one calculator in. What are you gonna do if it stops working? You don't wanna have to waste time changing the battery.
