ORDINARY LEVEL

GENERAL GUIDELINES FOR EXAMINERS

1 . Penalties of three types are applied to candidates’ work as follows:

Blunders - mathematical errors/omissions (-3)

Slips- numerical errors (-1)

Misreadings (provided task is not oversimplified) (-1).

Frequently occurring errors to which these penalties must be applied are listed in the

scheme. They are labelled: B1, B2, B3,…, S1, S2,…, M1, M2,…etc. These lists are not

exhaustive.

2. When awarding attempt marks, e.g. Att(3), note that any correct, relevant step in a part of a question merits at least the attempt mark for that part if deductions result in a mark which is lower than the attempt mark, then the attempt mark must be awarded a mark between zero and the attempt mark is never awarded.

3. Worthless work is awarded zero marks. Some examples of such work are listed in the

scheme and they are labelled as W1, W2,…etc.

4. The phrase “hit or miss” means that partial marks are not awarded – the candidate receives all of the relevant marks or none.

5. The phrase “and stops” means that no more work is shown by the candidate.

6. Special notes relating to the marking of a particular part of a question are indicated by an

asterisk. These notes immediately follow the box containing the relevant solution.

7. The sample solutions for each question are not intended to be exhaustive lists – there may

be other correct solutions.

8. Unless otherwise indicated in the scheme, accept the best of two or more attempts – even

when attempts have been cancelled.

9. The same error in the same section of a question is penalised once only.

10. Particular cases, verifications and answers derived from diagrams (unless requested)

qualify for attempt marks at most.

11. A serious blunder, omission or misreading results in the attempt mark at most.

12. Do not penalise the use of a comma for a decimal point, e.g. €5.50 may be written as €5,50.
