Can you still get the marks if you write two answers?Watch
LOL I MEANT TWO NOT "TO"
But in general, if you give two different versions of the same number, you would not be marked down. If you gave two different answers, you would not get the marks even if one is correct.
Really? I have always been under the impression that including an alternative to a correct solutions indicates that you don't really know what you are doing, and that you are hedging your bets by including alternatives, which would therefore disqualify you from any marks. I mean, if you show a correct method and an incorrect method, who is to say which one you wanted to be assessed?
If a candidate makes more than one attempt at any question: If all but one attempt is crossed out, mark the attempt which is NOT crossed out. If either all attempts are crossed out or none are crossed out, mark all the attempts and score the highest single attempt.
If there are two or more attempts at a question which have not been crossed out, examiners should mark what appears to be the last (complete) attempt and ignore the others.
These are both from the mark schemes which are freely available on the exam board websites.
