Biology GA1 Results!

Hey guys just a question how did you work out your Ga1 total?

It got published on my school's intranet page for my subject results (82% for GA1)

Hey guys just a question how did you work out your Ga1 total?

All your unit 3 SACs total to 100. Just add all your marks! Or ask your teacher

It got published on my school's intranet page for my subject results (82% for GA1)

Great result! What's your rank?

Great result! What's your rank?

No idea. There's about 45 Bio students at my school and a significant amount have scored worse than me, so hopefully I'll be able to achieve over a 30! I'd be happy with that

Sinse i know my percentages couldnt i just add them all up and divide them by 5? eg in order my results for bio have been 72%,83%,88%,87%, and 88%. so when i average them out my score it is 83.6=84. Would this be my Ga1 result 84?

Not necessarily, as some SACs were worth more marks than the other. So you need to add all your marks, not percentages.

For example 12/17, 15/16, 19/25, 16/17 and 24/25.
As all the SACs totalled equal to 100. Adding them will result in 86/100 = A.

Asked my teacher today has said my GA1 is 85. Is this any good?

[Reus]

Higher than mine! Congrats

how highly/lowly (if thats a word) can VCAA moderate your sacs?

Mine were moderation 15 marks up for each unit. So 30 in total.

They can go down, can stay the same, or go up. Depends on your cohort + how well you do in the exam

Are you sure that's how you calculate your raw GA1 score? I thought it was something among the lines of this:

Hypothetically speaking,

First SAC, worth 60% you received 19/20
Second SAC, worth 30% you received 18/20
Third SAC, wroth 10% you received 15/20
Then your Raw GA 1 score would be = .6 x 95 + .3 x 90 + .1 x 75 = 91.5%

As opposed to the average which would be ~ 87%

Correct me if I'm wrong

That was the case with my methods SACs. However for biology, my teacher made all SACs equal to 100, so the GA mark would be your SAC marks accumulated.

I know people have explained this over and over again, but I'm just making sure.
I got 88/100 for unit 3 and I'm ranked first in a weak cohort. Does this mean that if I stay rank 1 for unit 4, I'm not effected by my class, and If I got 100% on the exam (not going to happen) I would get a 50 ?

Yep. Moderation generally will not affect the top one or two students if they drastically stand out from their cohort.
VCAA use marker points, i.e. 4th student, 10th students and 16th student to know how to scale not only the cohort as a whole but even segments of the cohort as well.

94/100 for unit 3 and ranked solid 2nd in a weak cohort...are my chances of getting a 40 out of reach (assuming that I maintain my marks of course)? 

Also, according to the graded distributions (http://www.vcaa.vic.edu.au/Documents/statistics/2013/section3/vce_biology_ga13.pdf), only 94+ is considered an A+?
