Hahaha. that actually happened to me in 2003. My teacher decided to do Bio genetics Option and had a hard exam for it so I ended up coming 2nd in the school. The other class did the easier exam for the Option and a girl came first. Her assessment mark was 93, mine was 92. In the HSC exam...

Nah, Guy wasn't the favourite from the start. Cosima and Paulini were.

yes I agree with you. Jess is just not improving since her first touch-down performance with the Christina song. She is still pitchy and can't sing well on her lower register. Damien is improving each week but should have done better in the final. I was rooting for Jess until half way...

Personally, Jess only gave 1 good performance - the winner's single. Both of her other songs weren't that great. She picked the wrong song for the second performance. It didn't suit her. Her third performance was only slightly better. Overall 7.3/10 Damien's winner's single was out of tune...

Generally, no specific question will be based on preliminary skills, but the knowlege you gain from doing 1 year of biology in the Prelimin course should be applied to your HSC studies. And that's what the 8-mark question requires you to do.

I have read over the paper and it's a fair paper. Most of the questions are not difficult if you have actually go over the syllabus and study well. Difficult questions, such as the 8-mark Warren and Marshall's experiment on Helicobacter pylori is more demanding because students are required to...

Since you are ranked first, you will receive the highest exam mark as your school assessment mark (yours or someone else's), and your exam mark as your exam mark. The average of the two gives you your final HSC mark.

In that case, you will receive your own exam mark as the HSC exam mark, and the lowest exam mark from your school to become your school assessment mark. e.g. You came first in the HSC exam with a mark of 95. Your ranking in the school is last. The lowest exam mark from your school is 60...

But molecules don't have subunits! Only proteins do!

If his raw exam mark is 100, then his reported exam mark will be 100. This won't change. This will then be combined with his school assessment mark (which will be similar to the second highest exam mark in his school since he is ranked second) to give him a final HSC mark. Please note that...

By saying it is a molecule, it doesn't tell me anything about it. I think the examiners are looking for the key word "protein", which is found in RBCs and function to carry O2. If it's a 2 mark question, may be you also need to say that it is composed of 4 subunits, 2 alpha and 2 beta.

Yes, in that case you must talk about the Koch's postulates. You will probably lose some marks for not mentioning them. In reality, they did have evidence that demonstrate the first two postulates. However, in this case, you would have to base on the information they give you. Barry was...

The 8 mark question appears to be very interesting based on the discussion here (not exactly sure what they asked). Did they mention Marshall and Warren and their Nobel prize for demonstrating Helicobacter pylori as the cause of stomach ulcers or something? Marshall was trying to...

I would have put down lactose intolerance down as a genetic non-infectious disease. I think nutritional non-infectious diseases are diseases where you don't get enough of a particular essential element, like vitamins. In lactose intolerance, these individuals do not produce enzymes...

It depends from year to year. It will be up to the judges who determines the final cut offs for each band. Okay, there seems to be some inconsistencies with Q 5, 8, and 9. Q5 is C; Q8 is B; and Q 9 is D. Generally I think the multiple choice section has some very interesting question...

Sorry for the inconvenience. I don't know why the Bio exam forum is still not opened. I have no control over that. In the mean time, you are welcome to post your exam thoughts here. What was the most difficult question?

Unfortunately the exam forum for Biology is still not opened, which I have no control over. In the mean time, discussion of the exam in the normal Bio forum is more than welcome. So how did everyone go? Predictions? Any Band 6's? I have not seen the paper so I wouldn't know how difficult...

No, only dendritic cells, B cells and macrophages have MHC Class II on their cell surfaces. These are known as professional antigen presenting cells.

If it is an X-linked recessive disease, you should see that in all cases, an affected FEMALE will pass on the disease to ALL of her MALE offspring. This is what you look for. In order for female to get the disease, the father MUST be affected, with/without the mother being affected. In normal...

It's fine just know everything in the manual. But just know it well. Some of the questions you can't really study for anyway. For example, they will put a pin in an organ of a dissected rat/toad and it will ask you "What is the Function of this organ?", and questions like that. You bascially you...
