    Ipod greatest invention ever?

    There are many mp3s/phones that are "easy to use, stylist and consumer friendly" (entirely subjective). That doesn't warrant the iPod to have it's own category. It just isn't that unique. The only reason the iPod is so popular is because of its marketing.

    Ipod greatest invention ever?

    Well you're using the term quite loosely. I don't think the Ipod brought anything new when it was released. It's like saying the new nokiaNXXX is a invention. What makes the Ipod stand out from other mp3s?

    What mark do u need to get an E4 in 4u?

    When i say piece of cake I mean, for example if u accelerate 4units of math, then during yr 12 u can do only 6 units. This will obviously greatly reduce your workload. Or you could do some other subjects of interest.

    What mark do u need to get an E4 in 4u?

    That's fail man. You should accelerate, just because u accelerate in 3 units doesn't mean you wont see your grade. If you accelerate, it will make your yr 12 a piece of cake.

    You 4 unit maths guys! Why?

    Why did/are you doing it? I am good at math and enjoy it. Furthermore its reduces the total amount of different subjects I have (counting 4u as 1 subject) and reduces the amount of rote learning memorization regurgitation subjects. What's your motivation? Friends/good marks/scaling How did you...

    Combination/Perm Q

    technically there are 4 slots between the girls. but two more on the end(one on left one on right) so there's 6. If you use ur hand (with fingers being girls) Theres 4 spaces between fingers, and two slots on the sides of ur hand. If there were some condition that said "the boys cannot occupy...

    Combination/Perm Q

    Insertion method. You can arrange the girls in 5! ways. Now you "insert" the boys between the girls. There's 6 slots u can insert between the girls. Since you have 3 boys, you choose 3 from 6 slots. 6C3. Since u can rearrange the boys u multiply by 3! = 5!6C3 x 3! = 5!6P3 It's easier to...

    15% of Prelim maths counting for hsc o.O

    None of your preliminary mark counts to HSC. However 15% of preliminary knowledge can be directly tested in HSC math.

    Best MX2 textbook

    Cambridge only negative is that it doesn't have harder questions and thats a BIG negative. Terry Lee has hard questions, but some are just too hard that will never come up in the HSC. One thing I will say: ALL 4u TEXTBOOKS DO NOT FOLLOW HSC FORMAT.

    can assesment marks be excluded as outliers

    Ur comment is somewhat contradictory : S ? Wouldnt excluding outliers not reward one-hit-wonders.

    08er Tutor for Chem/Phys/3u/4umath

    Thank you Zeph :) My school doesn't actually give very good uai projections. The top UAI projection is actually 98-100 given to the top 20 students (yeah I know it's stupid) I want to do engineering in uni so I don't feel very pressured to gain an extremely high UAI. Anything over 99 would be...
