Yea i heard from a hsc marker that they only decide marking guidelines and decide what constitutes a good answer after going through lots of papers. Fingers crossed for the photocell but i honestly think we may end up losing at least 3-4 marks :(

Wow! is that possible?! I thought the photocell question and astrophysics ruined my chances of above 92 :(

Yup thats what i said

hey does anyone know what 84-85 raw would align to? cheers.

gosh astrophysics + photocell question just ruined it all. Anyone know how an 84-5 raw mark would scale?

So does this mean we won't be marked down for solar cells? Please please let this be true....

Oh no! I mixed up photocell with solar cell asjhjfkhdakjf failllll does anyone know how many marks i could get? :(

I also thought it was much more difficult then past papers! could not work out how to measure mass or luminosity! mindblank...

Hey does anyone know what the worst exam mark is that a raw mark of 85 would scale too? Cheers

Hey, I'm not quite sure how to do this question. Can someone help me get started? If in the oxidation of a sample of glucose to carbon dioxide and water, 4.06 L of carbon dioxide, measured at 101.3 kPa and 298 K are evolved, how much energy is released?
