My thoughts exactly, it's one test so you would think they would make it awesome.

Also good job with the eco paper.

I was think of making a 2U paper in the new format...

yeh that's what is worrying me, because I'm starting to think that by asking for an approximation they were expecting decimal answers. (2.0 ? lol)

Yeh I also put 2. imo it was a very bad question, there should have been no estimating and the graph should have been a little better constructed.

If they don't specify, we are both right as you acknowledged your answer wasn't 100% by saying (2 d.p) and we got it exactly.

It's a lot better if you choose extension and then drop later rather than not choose it and regret. Choose it, then drop if you need to later. Worth the effort? hell yeh Too much to handle? depends on mathematical ability (but its only one unit) More beneficial than 2 unit? depends what...

Or suggestions for questions or question types from users, as through study they may find trends or parts of the syllabus not addressed enough.

Yeh in this case it is both like you said. In any velocity/time graph, the area is the total distance and the integral is the total displacement. In this case, area = integral. Hence distance = displacement (from 1 to 0 seconds)

No your right because if the area is all above the x-axis, then the displacement in equal to the total distance travelled. So either displacement or total distance should get the mark.

+1 That's why squats are considered one of the best, if not the best, exercises you can do. Quads are such a large muscle, working them would benefit your whole body due to testosterone released. Also while performing a squat so many other muscles are used.

It's only a lot of money when the student doesn't try, then it's a waste. But if the student tries hard and improves, then it's a solid investment.

+1

yeh exactly, they walked you through it.

haha i did the same thing, though i dont remember is asking for 2 d.p.

Nope 2U people are more than capable of doing the exam. They didn't use extension identities, rather they used 2U stuff to prove a 3U identity, then after it was proved, it was used to answer a question in which you were given the answer. (i.e a 'show' question) I used to think the same thing...

It's not too bad, but everything depends more on rank.

Yeh it was close but a teacher told me that it's suppose to cut at 3. Bad graph imo. yeh it was a really shit graph

Not really the graph was supposed to cut the x-axis at t=3. Hence the velocity was 0 at that point.

Yeh not sure why so many got stuck when you found HK^2 twice, clearly you had to use it. People seem to forget that when they help you through a question, most likely every part will be used again in another part.
