Further Exam - Are we meant to show working out?

[omesha124]

Hi,

On some questions on the Further Math 2 exam, I only wrote answers instead of showing full working out. I worked some questions on CAS (such as finding the maximum score for graphs and relations), but forgot to write 'found on CAS'.

Will I lose marks even if I have the correct answer?

If a question is worth only one mark, you only need the answer. If it's worth more than that you will need to show more working out. Generally speaking writing 'found on CAS' won't get you any more or less marks because they can't actually check your calculator method if your answer is incorrect.

I found this in the 2014 examination report: Full marks were awarded for each complete and correct answer, whether or not this was accompanied by working. For a two-mark question, if the answer was incorrect, working out may have earned a method mark, but such working needed to clearly show a significant, logical and correct step towards the question solution.

I am confused. I know that throughout high school, our math teachers always told us to show working out in case we get the answer wrong, but have a correct method - from what I have seen, losing marks for not showing working often comes with questions asking for percentages, or requiring rounding.

Can anyone else put their two cents in, because I am so worried.

That's mostly correct, however I believe with Graphs and Relations in particular you need to show working as part of the assessment criteria or whatever is algebraic manipulation. Getting the correct answer generally implies that your working out was adequate so I wouldn't worry too much. In any case further's done and dusted now so getting worked up about it is unnecessary stress. ofc someone more knowledgible about how further exams are marked would probably give you a more concrete answer.

when i did further in 2014 if you got the question correct even if it was a 4 mark question and you showed no working out you still got 4/4 but if you showed working out that was logical and your final answer was wrong because you fucked up somewhere youd get 2 or 3/4. basically you dont need working out but its a good safety net
