<p>"btw what about the speed of the waves passing the boat? I can't remember whether I took the length of the boat as half the wavelength or one wavelenght...so what was it?"
I'm pretty sure it was crest to crest, so one full wavelength.</p>

<p>"I can't believe I used my left hand thumb instead of the right one for the electron flow-magnetic field question!"
Which question was this? Was this the one that had electrons moving in a wire and asked for the magnetic field? It didn't really matter which hand you used because the answer was "perpendicular to the page", right?</p>

82

<p>I put perpendicular too and I think I used right hand rule</p>

83

<p>i put perp. i think</p>

84

<p>what about the question with ...two points are out of phase with the wave...what will put them into phase or (something similar to that question)</p>

85

<p>i think thats 180 degrees</p>

86

<p>'i think thats 180 degrees'</p>

<p>no the choicees are like: half the wavelength (which is wat i put =.=) one fourth the wavelenght, etc...</p>

87

<p>ya sry thats what i meant. i also put 1/2 wavelength</p>

88

<p>1/2 wavelengths is correct</p>

89

<p>That's strange...I totally do not remember that question.</p>

90

<p>I think the jumping ball one was E (eliminate all lose in energy)</p>

91

<p>did u guys start to get a lot of E's toward like the middle end? for some reason i started getting tons of Es</p>

92

<p>I had a HUGE amount of E's</p>

93

<p>good yay :) so if u fail that means i fail too right ? :-/</p>

<p>"Desbravo, I agree with all your answers in Post #44. I don't agree with your assessment of the A-levels, however. American universities do not consider an A on the A-levels as an A+. Nor do they do any such silly conversion system. Even if they did do this, what would they do with the A+? Put it on your first semester report card? Anyway, I can't vouch for the difficulty of the A-level exams (there used to be this site that posted past A-level exams, but I can't find it anymore). But, a British classmate of mine takes the IB diploma and claims that it is harder than the A-levels.</p>

<p>Also, if you could answer this one question of mine...does A-level physics touch calculus? I've been trying to find out, but I couldn't find anything."</p>

<p>Well said. In fact, British A-Level is a joke compared to the one given in Hong Kong. For the British A-Level, 21% of letter grades are As (you only need 80 percentile to get an A) which sounds no more difficult to get than 700+ on SAT II.</p>

95

<p>well i am just telling you the conversion system i found on the Cambridge international examinations website. i was just comparin them to american education. not hong kong education. And an A+ is not supposed to get on ur reprt card but is supposed to help u in the admission selection process. besdies and A+ also enables u to skip the beggining courses in the uni.
and a le ve l physics does touch calculus but only when deriving equations</p>

96

<p>Maybe A-level Physics doesn't touch calculus, but A-level Mechanics sure does. A lot.</p>

97

<p>aleve physics just touches calculus. In alevel mechanics u have to do calculus</p>
