I didn't rank so well in English when I did my HSC, (50+), but I managed to just scrape a Band 6. But then again, my School owned English that year and did quite poorly at Sciences (top 10 rank for Physics and got a low Band 6) So It depends what subjects your school also excels in. (Teachers...

Totally recommend using dot points especially for the sciences. There are many good books for sciences, which include DOT POINT and DOT POINT (multiple choice) and there are also the excel revision guides, that are now by syllabus dot points. But still utilise your textbook, they are much...

Everyone is much more comfortable just keeping up with class at school. However, the problem with this approach is that the exams usually test what you learnt last week in class, leaving you with little time to revise. That is why it makes sense to go ahead (especially in Maths & Sciences)...

I find that having a daily plan is really handy, especially for the holidays. The night before, on a piece of scrap paper, just write down what you want to achieve tomorrow, and during what times that is (e.g. trial paper from 9-11am etc). Make sure to schedule in some relax time & exercise...

Discuss the importance of Newton’s Law of Universal Gravitation in understanding and calculating the motion of satellites * Newton’s gravitational equation can be used to derive equations that let us calculate or predict the orbital velocity of planet’s, moons and artificial satellites by...

* Scientific discoveries are rarely the work of individuals, but tend to be teams who share and collaborate their findings in order to efficiently make a discovery. The discovery of DNA structure is a good example of effective communication and collaboration in scientific research. * Watson and...

Beadle and Tatum used bread mould to investigate nutritional mutations. Using X-rays, they produced mould that was unable to produce a specific amino acid. The mould was unable to grow unless the amino acid was added. They showed that genes controlled biochemical processes. Their hypothesis was...

Renal Dialysis is primarily used to provide an artificial replacement for lost kidney function (renal replacement therapy) due to renal failure. Dialysis may be used for very sick patients who have suddenly but temporarily, lost their kidney function (acute renal failure) or for quite stable...

Chemical composition of enzymes: * All enzymes are made of globular protein * Proteins consist of one or more polypeptide chains * These are composed of long chains of amino acids joined together by peptide bonds * Amino acids consist of an Amino Group (H & N), R Group (Organic substituent)...
