Na dw, happens to everyone. Its called 'clouding of consciousness' and medically referred to as delirium, which I can get susceptible to sometimes. Usually for me its because I haven't had the caffeine for few days.

It depends really. It depends on my state of mind. If I am able to think right at that time and have proper concentration with no 'mind cloudiness', then I probably can do the questions but if my mind is not in the right state, then I am screwed.

I meant HSC past papers. School papers too but I don't look around to see who is done so I just sat there and checked my work in school trial.

No. Quanta have frequency, and thats why you have threshold frequency.

Well I am here. And it's usual except 2010 and 1993 which was 30 mins early.

Can anyone please provide me with 2005 CSSA 4U solutions by PM?

Isnt bio basically an english essay session in terms of writing? If you did that for 4U, then I could understand, but you are crazy if you can do that for the sciences.

Thanks a lot! Would rep, but doesn't let me. If someone can clarify med phys that'd be great.

Would love to try that. Although not sure if in syllabus. More than 3/4 of the state however are not proficient with circular motion with variable angular velocity. However it hasn't been asked for a long time now. I doubt it will pop this year.

Oh and btw for 27 c): I though photocells use photoelectric and solar cells just have valence to conduction transition? And for Med phys students: for 29 a) i) The photographic film should appear whiter with greater attenuation from barium meal right?

I would've enjoyed it. I have got engineering in my blood from ages. But I want to be a surgeon. Thats even better. The greater the difficulty the more you enjoy to learn, cos you dont want to go to school for something that you dont learn from..

Engineering looks interesting from the quick skim though the book. Should've tried it in yr 11, although I just wanted 10 units.

Agreed. An easier way to say it is 'English is shit'. Although no body wants to hear the word 'English' in itself.

Thought perms and combs was 3u. Hope Perms and Combs are swapped with something like harder mechanics.

Yes Thanks.

No you are right. I should structure. Thanks.

Have some confidence. Its Australia and there are endless opportunities to get into courses esp. IT because its a booming industry and the demand is high so you will be fine.

Yes, Harwood was quite difficult because there is a certain requirement to use the extract and people who didn't would go lower. Frankenstein: people found it hard this year.

w0t, if e=mc^2 + 1/2 mv^2, and that the increase in energy is from the increase in relativistic mass to external observer, but the relativistic mass in both frames is different, hence you might be contradicting yourself on the energy part? Pretty sure my bolded part is based on rest mass and the...
