The paper directly said only to attempt 1 question from section B. But, I done both the questions on section B. How do they mark it then. Do they give me no marks at all for section B. Even though its potentially correct on both?
For example, Section A has 6 questions and you need to answer any 4. You answer 1,2,3,4 and 5. The marker would mark questions 1,2,3 and 4 but because only 4 questions are required to be answered they would skip question 5. If you answered out of order, say 2,4,1,6,5, then 3, they would mark question 2,4,1 and 6 and skip 5 and 3.
Hope this helps but you should definitely check the module handbook or ask the module leader for clarification.
