you have to apply for it to vcaa and they'll send it to you. its just an additional thing you can do if you're curious about your mark+where you went wrong.
search on google 'statement of marks'  and click the second entry (pdf file) -thats the application form you can send.

Just wondering, how does cohort effect the SS?

A more detailed answer on the calculation of study scores is available here:
http://www.vcaa.vic.edu.au/vce/exams/statisticalmoderation/statmod.html

More or less, your SAC scores themselves don't go into the computer, your rank relative to the rest of your class goes in. Then, the top exam score gotten by someone in your class will be equivalent to the top SAC score (which might not have been achieved by the same person). You always keep your own exam score. The link above is much more comprehensive and I recommend that anyone who is interested in the VCE read it.

Also,
there's like 100 threads related to this...
It's getting there. Haha.

There was an awesome explaination somewhere, and I was going to quote it, but I forgot who posted it/which thread it was in.

Here is my dodgy explanation (better off clicking the links above in my opinion):

Basically, if your cohort is strong (i.e. smash the exams) your SACs would be moderated to suit this. Let's say someone goes to a really poor performing school (bad on exams) but everyone gets really high on the SACs. Come exam time, all the kids in that poor performing cohort screw up their exams. VCAA would then think: "oh that school must've had really easy SACs since they did so bad on the exam but got really high in their internal assessments (SACs)". Like a B+ at Melbourne High School for a particular subject's SAC could mean A+; and the same B+ at (lol I'm sorry I'm going to have to pick a public school to stereotype) Pakenham Secondary College* could actually mean a C. It depends on how you rank in your class and the exam scores that the cohort gets. If you were rank 1 in SACs and getting A+'s, and then get really high on the exam then your SAC mark would still be high to reflect this. It's the process to determine which SACs were easy and which were hard; since everyone does the same exam but different SACs. You keep the score you got on the exam for the relevant GA because they don't need to be moderated further as everyone sits the same exam.

*blame this not me.

So, if I did the best on the exams and rank 2 in SAC's, I would take the 2nd ranks exam score for my SAC's? :S

Well after some slight statistical moderation, yeh, pretty much AFAIK.

yeah a 62.5 which is low a+ i think....???? paired with a high a+ end of year could probs easily get you above 45
Title: Re: Biology Statement of marks
Post by: qshyrn on August 20, 2009, 08:13:45 pm
62.5=definitely a low A+
i spot a 1 mark question where the markers marked it wrong(both of them), and i should have gotten the mark!!!
it was q 5g, and i wrote Phagocytosis......  (which is endocytosis, except for solids...)
Title: Re: Biology Statement of marks
Post by: lukeperry91 on August 20, 2009, 08:18:32 pm
Yea that's what they teach you at tsfx, I however decided to stick with convention and wrote endocytosis to avoid your situation :P

I think that's because phagocytosis more refers to the ingestion of larger solid particles such as on a more cellular level such as bacteria, viruses, debris from lysed cells etc, as opposed to biomacromolecules. If it referred to the ingestion of protein molecules as in the diagram, almost anything could be classified as phagocytosis given that there's usually some solutes in the ECF.

thats gay, my bio teacher once said that "phagocytosis" is more accurate than "endocytosis", when its ANY solid grrrrrrr...... >:(

"It's not a low A.. its a mid A+ errrrrr check your sources before you talk"

wow dude. obvious typo.. and yes, its a low A+

wikipedia
Types
There are three main types of endocytosis that are distinguished by the size of the vesicle formed and the cellular machinery involved.

Phagocytosis (literally, cell-eating) is the process by which cells ingest large objects, such as cells which have undergone apoptosis, bacteria, or viruses. The membrane invaginates enclosing the wanted particles in a pocket, then engulfs the object by pinching it off, and the object is sealed off into a large vacuole known as a phagosome.
Pinocytosis (literally, cell-drinking). This process is concerned with the uptake of solutes and single molecules such as proteins. Both phagocytosis and pinocytosis are non-receptor-mediated forms of endocytosis, and may result in the cell engulfing non-specific or unwanted particles.
Receptor-mediated endocytosis is a more specific active event where the cytoplasm membrane folds inward to form coated pits. In this case, proteins or other trigger particles lock into receptors/ ligands in the cell’s plasma membrane. It is then, and only then that the particles are engulfed. These inward budding vesicles bud to form cytoplasmic vesicles. This process may also result in engulfing of unwanted particles, however not to the extent of pino/phagocytosis.

Wait how do you know if you got a low, medium or high mark once you have your score out of 75 or whatever it was?
I don't have mine yet, but when I do get it, how will I deduce my position from what I'm given?

What is 70/75?
Is it a high A+?

yep pretty high as in 46-47+ if that's what you're after.

Yes, I really want to get 48...
It's actually my life goal to beat this girl from last year's cohort that I hate more than anything ever.
Yes.
Yes...

Thankyou :)
