Out of 75

[thushan]

How about their SACs scores and end of year exam? Close to full mark?

Um, the both of them were rank 1 and 2 in their respective schools I think. One of them (the dude who got 63) got like 73.5 on the endofyear.

but each year, A+ cut off is different though == depending how hard exam papers are and students' performance

Is there a way we could check 2010,2009 cut off for A/A+

10: A: 53, A+: 59
09: A: 55, A+: 60

Thanks. Why is the median always C+ , does it mean that is the most common grade received by students? I think this yr cut off for A+ will be around 61 then.

Hi everyone,
My teacher is an examiner, and if it is helpful, she thinks that they will have to cut the question (or give everyone the mark) for the last question NADPH vs. Oxygen (the one where it asked for a compound).
Also, she thinks that they may have to give everyone the mark for the MHC1 multiple choice question because it isn't in any of the textbooks and it isn't technically part of the course.

She's not sure (obviously!) but this is what she thinks

[LOLs99]

Which MC is that? I can't remember any mhc thingy. I wrote oxygen and know it definately right but just vcaa trying to trick us and put compound? Maybe vcaa should award the mark for polypeptide and the explanation for that question because I can see it as a different way.

[InsaneMcFries]

If you can explain your POV in the polypeptide question I think it should be variant.

The MHC marker question SHOULD NOT be cut. It is a general conception that an MHC marker will present foreign antigens, class 1 or 2.

The compound Y question should award marks for oxygen or NADPH or whatever as well, to be fair on chemistry students.

[LOLs99]

oh that mhc question was  assumed knowledge though.
I'm just worried with the polypeptide question now, if they mark me wrong then that means i lost 4 marks in a page

Hmmm with that polypeptide question, I explained that at low temperatures it's inactivated and at high temps it is denatured. My graph is incorrect, but wouldn't they still award marks for the explanation because it is still correct?

And yes, but MHC2 markers are commonly accepted as the foreign antigen presenters - MHC1 markers are less well known as presenters. I think that there will be a bit of a discussion (I'm hoping it will be cut though!!).

That's probably a fair point - they'll award marks for either oxygen or NADPH.

in the same boat for the poly-peptide question, i said even tho there is low temps, the polypeptide is not denatured therefore can still perform its function and i said that other was denatured

I agree with you. Students should distinguish between MHC 1 and 2 because foreign antigens cant have MHC 1 anyways
And compound means more than 1 type of atoms as our teacher taught in chem so Y cant be oxygen even though it seems to be the correct answer in this diagram

As unfair as it is, NADPH cannot be an answer. I think they'll most likely just strike this and give everyone a mark/not count it.

The graph clearly showed that compound Y was used in the electron transport chain of aerobic respiration. NADPH, although a product of the light dependent reactions of photosynthesis is not used in aerobic respiration. NADPH is not a correct answer. Really, there was only 1 correct answer, but it was made ambiguous by the fact that oxygen isn't a compound.

I understand the ambiguity of the question, but NADPH is not right. Mostly likely they'll have to strike the question and give everyone a mark.

Yep you are right. NADPH produced in light dependent stage but NADP not NADPH used in cellular respiration.
Actually as Douchy explained on his podcast's page, there is no right answer for this question and he will notice VCAA about that
