Which spelling is accepted as correct, the American spelling or the British spelling?
Both are accepted as right, but a candidate should remember he should stick to either one of the two and not use a mixture of ‘American Spelling’ and ‘British Spelling’. If you write ‘rumour’ it means that you are following the British way of spelling. In the very next line, you write ‘color’, which means that you are following the American way of spelling. Don’t do that, stick to any one form.
