Getting the right answer, but then getting it wrong with further working (2 Viewers)

[~ ReNcH ~]

nope, ruse makes their own trials, which dont really look much like the real thing (apart from the fact that its got 8 questions, each out of 15)
umm, q7 and 8...just staring at it wont work, but staring while writing things on scrap paper might
but still, its more the second thing u mentioned

Ah ic...
Is there any sort of pattern for Q7, 8? Coz in Ext 1, you can almost always bet that Q7 will be Physical Apps, Inverse Trig or Binomial...just wondering whether they test the same topics for the latter exam questions.

Referring to the marking guidelines:

Many responses did not clearly identify the remainder as R(x) = 3x – 8 and a frequent concluding statement was P(x) = Q(x) + 3x–8. Other candidates believed that the remainder needed to be constant and solved expressions for a(x+1) + b = 0.

From memory, I did find the remainder to be 3x-8, however in working further I did for some reason work that remainder down to a constant as stated in the marking guidelines...

Something tells me I've asked this before:

Suppose you write a few lines of working and get the right answer unknowingly, but because you're unsure you continue working and end up with the wrong answer, are the markers instructed to stop marking and award the student full marks? Or are marks "deducted"?

Okay, sorry, I may have given incorrect information:

That is correct.

As long as you provide the correct steps in your working, all other incorrect methods are disregarded.
In this case, you have shown the markers that you are competent to deal with that question (you have just done superfluous working).

However, taking this approach puts you at a disadvantage as it wastes time.

This is not entirely accurate.

(In the following, 'proffering' means leaving as an answer.

After speaking with Rosie (who marks HSC papers):
If you proffer the correct solution, you get full marks (obviously)
If you write an incorrect solution, but cross it out, and proffer the correct one, you get full marks (obviously)
If you write the correct solution, but cross it out, and proffer an incorrect solution, you receive a one mark penalty (if the question was out of 1, you get 0; 2, 1; 3, 2 etc).
Suppose you write the correct solution, cross it out; then, write an incorrect solution, cross it out; then proffer another incorrect solution. This will result in a two mark penalty.
Similarly for three incorrect responses.

If you simultaneously proffer an incorrect solution and a correct solution, you receive a one mark penalty.

(Basically, you receive a penalty for each incorrect solution for which you give an equal or higher status (proffering is higher than crossed out)

(By the way, you cannot receive negative marks for questions. )

Hope that clears everything up.

(Just write the correct answer. )

Hmm...although I thought the HSC markers were under instruction to award marks for correct working as opposed to taking away marks for incorrect working...
On the other hand, I heard that you could potentially write several "alternative" solutions to the one question and if one of them is correct, then you aren't penalised at all.

Although, if that is the case, then I probably lost that one mark which kind of sucks.

 

[~ ReNcH ~]

If you simultaneously proffer an incorrect solution and a correct solution, you receive a one mark penalty.

In this case, does this refer to two distinctly different methods of solving the question? Or does it also include the situation in which you give a correct solution but continue with the same "method", resulting in an incorrect final answer?

If you wrote two distinct solutions using exactly the same method, and made an arithmetic error, I am pretty sure the markers would write ISE and award you the mark.

However, if you proffer another method which is invalid or otherwise not correct, you stand to be penalized one mark.

Students who achieve the required step are awarded the mark, which then cannot be lost for a subsequent error.

"Those who provide sufficient evidence that the appropriate step, or its equivalent, has been completed are awarded the mark, which then cannot be lost for a subsequent error."

Like the quote at the end of your post...where's the line drawn between an error and a "further method", unless "subsequent error" merely refers to arithmetic or transcription errors?...but this would not likely happen unless the student continued with further working anyway, since they would naturally stop writing upon getting what they believe is the right answer.
