I just need to have a little rant to express my annoyedness. In every exam I have had so far (MX2, MX1, Physics, English Adv) I have made some incredibly dumb mistakes which are frustrating me so much. Like today, for example, in Physics I think I have lost up to 10 marks on poor errors such as...

Analyse the relationship between the position of elements in the Periodic Table, and the acid-base behaviour of their oxides (4mrk)

if that. i reckon around 73. they mark the theory so harshly

In, say, a 3 mark question, say you make an error in the initial step of the calculation. If the rest of the calculation is correct according to your incorrect value, do you still get 2 marks like maths, or because of the strict marking criteria do you get 0?

With your answer, it's all good except when you mention Lenz's Law, state that the induced current opposes the change in mag. flux and hence the induced currents occur in the opposite direction to the motion of the current in the magnet. Otherwise, your answer does not makes sense. You are...

no, because it starts initially perpendicular to the magnetic field

different gas pressures within the tubes

Do markers mark everything on the page, or just up to the end of the lines in Physics and Chem?

In the current generation prac, HOW were variables held constant? I came across a question which asked this. I knew which variables were held constant, but I didn't know HOW they were held constant. Anyone know?

A satellite is to be launched into a geostationary orbit. Given that the Earth's radius is 6.38x10^6m, calculate the height of the satellite above Earth's surface (3m) Anyone know how to do this?

What are transistors/ how do they work/ what do we need to know about them?

thanking you :)

What are they, how do they work and what do I need to know about them?

nope. it's B. so how did you do it?

How do you do question 20? http://www.boardofstudies.nsw.edu.au/hsc_exams/hsc2010exams/pdf_doc/2010-hsc-exam-chemistry.pdf

Ok, so I know that with the BCS theory of superconductivity, the temperature must be below the critical temperature to allow for the formation of Cooper pairs. These low temps are required for the repulsive forces of the electrons to be overcome, attracting each other to form Cooper pairs and...

In relation to the first question, I would talk about how the colour can help determine its surface temperature, hence alowing it to be plotted on the HR diagram where M can be found and hence its distance. Also, discuss how this plotting can calculate its mass and hence elements present withing...

All you people that are saying 60/70 cutoff are way off. Whilst the test was relatively easy and many people will have been able to achieve a mark of 60+, you are forgetting about all the small, rural schools and also the students whom do MX1, but aren't at the 'peak' of their cohort. Of the...
