Tehn underneath the diagram I talked about the process of reabsorption and filtration, what will I get out of 6?

LOLOL

I DID THAT TOO. not because i thought it was right. i just didn't know the other one.
I labeled the medulla wrong too though =( . gg

I can see how people would consider it an easy exam, as the questions were quite general. However these type of questions i believe are the hardest, because it means they are looking for a specific answer.

My teacher is an incredibly pedantic marker who has marked science HSC exams many times, and she says all markers are like that, so I think even though I felt I went ok, my mark will be lower than I think it is, due to how precisely they mark.

Multiple choice was pretty good though, changed 2 at the last minute and so glad I did because I'm pretty sure I changed them to the right ones.

The Biology exam was pretty funny since i totally skipped studying the part of the Kidneys and too bad for me there was a 6 mark question on it!!!!
During reading time i heard some of my friends moan and laugh to themselves when they got to the part of "draw the kidney.... & functions...etc..."
Besides that part yeah it was a good exam, i guess.

LOL that was the question everyone was complaining about after we left the exam hall XDDDDD there was massive flipping of textbooks after

it wasn't about the nephron it was about the kidney. There are three sections to the kidney - cortex, medula and the renal pelvis. Thats what they were looking for in that question and what occured in each of those sites.

i dont think it can be B, because fungi are not killed by antibiotics; antibiotics kill bacteria.

[apple pancake]

[stormstealer27]

How many marks is it?? :S

I think it was only 1 mark, and you probably answered it because I'm pretty sure it had lines to write the answer on - like the space for the pedigree, and then the explanation thing was a separate question beneath.

This question was basically the exact dotpoint for the prac. I think it was research + becoming familiar with the plant diseases and their appearances, and then collecting plant leaves, etc to compare research info with actual specimens.

It was worth 3 marks not 1, assessing the validity of the student's claim that the inheritance pattern was that of sex-linkage.

i think the exam was okay
