Symbols in marking scheme and guide to writing a good answer

Symbols used in marking scheme:

/ - means that the responses are alternatives and either answer should receive full credit.
( ) - means that a phrase/word is not essential for the award of the mark, but helps the
examiner to get the sense of the expected answer.
Phrases/words in bold - means that the phrase or the actual word is essential to the answer.
Ecf (error carried forward)- means that a wrong answer given in an earlier part of a question is
used correctly in answer to a later part of the same question.

Guide to writing a good answer

1) Make the meaning of your answer clear to the examiner.
2) Make sure that the answer makes sense.
3) Answers must be in the correct context. In other words, your answers must answer the
questions.
4) Write legibly – the examiner must be able to read your handwriting and the font of your
handwriting should be big enough for them to read easily. Don’t forget, most examiners are
40s or 50s something and many of them are short-sighted.
5) Your words or sentences should have the accurate use of spelling, grammar and punctuation
in order to make the meaning clear.
6) Organise information clearly and coherently.
7) Use specialist vocabulary when appropriate.
