theyre all out of 80 rite??
wats the minimum grade for an A

physics was a lil bit not easy :P <<

Well, We still don't know the exact marks yet. Because it may curve down..  And yes they're all out of 80! :o

Good luck in Chemistry tomorrow

Peeps I got a couple of chemistry questions:

Why is it necessary to ionize atoms before acceleration?
and
Name the device used to ionize atoms in the mass spectrometer.

-you ionize atoms inorder to be able to deflect them and accelerate them...........if they're not in the form of ions you cnt accelerate them because there's no charge
-i dnt think they'll ask you to mention a device...........the Q will come in a way where they'll ask you to say how the atoms are ionized...........................they're ionized by bombarding them with a beam of high energy electrons which will knock off an electron forming an ion

The grade boundaries change from year to year.

cool so u mean that there are grade boundaries and that they r not fixed to 80% for example in math to get an A?

Thanks... Yeah I don't think they're going to ask that question, but oh well  ::)
