    HELP: Cocktail dress code

    Ok so my formal is coming up and the dress code is 'Cocktail'. I'm really not sure what that implies. Does that mean that I don't need to wear a tie? Is it ok to have wear a suit without a tie? I'd really like some help here.

    Question about Repeating

    I don't think that I will have to repeat but just in case, I was wondering what the procedure was. Is it possible to do all the studying by yourself and then sit for the HSC next year in an allocated exam center or do you have to go to TAFE? What if you don't need any lessons?

    Question about ext scaling.

    Ok so maths extension isn't exactly my best subject and I kind of fudged the exam. What do you think 55/84 would scale to? What band do you reckon that would put me into?

    SDD Marathon v1

    Simple. Post the solution to the question above you and ask a new question. It'd be a good idea to provide a solution for your question as well after someone else has attempted it to make sure that their solution is correct. I'll start it off. 1. Outline the three levels of testing...

    Help: Heuristics

    I've read several textbooks but in all of them the definition for heuristics is rather ambiguous and the concept is not explained very well. Could anyone enlighten me? By the way this is in the Evolution option and is a logic paradigm concept.

    How do you think you did?

    I think I did a lot better than trial. At least this time I completed the exam. I thought the comprehension question repeated themselves a bit but they were straightforward. The speech to Yr 7's was a bit suss but I managed to write 1.5 pages on it so I'm fairly satisfied. I did the...

    Questions on the journey essay.

    English advance and standard get to focus on just one type of journey (physical/inner/imaginative). Is that the case for use ESL students or do we have to discuss all of these? Also how much should you write about techniques? Would 2 techniques per text be enough? Is it important to...

    Extension speaking samples?

    I remember finding a couple of audio samples online of the continuers speaking exam. Anyone know where I can find samples for extension? (I'm not talking about past exams, I want the audio samples). Thanks.

    HSC: What band are you hoping for/aiming?

    I'm hoping for a band 6 but I'm not entirely sure I'll get it. I haven't done much work this year in SDD but I am now doing a few hours of SDD per day and will do so until the HSC so I think that I'm improving exponentially. What are you aiming for? And if you've already done the HSC what...

    Find the exact area bounded by the curves y=sinx and y=cosx in the domain 0<=x<=2PI. I don't know how to find the points of intersection (I'm tired shh).

    Inverse trig question

    When we are just given an inverse equation such as y=sin-1x, do we automatically assume that it is a function (ie: domain and range have been restricted) or do we treat it as an inverse relation unless otherwise told?.
