GENERAL MARKING GUIDELINES
1. CALCULATIONS
1.1 Marks will be awarded for: correct formula, correct substitution, correct answer with unit.
1.2 No marks will be awarded if an incorrect or inappropriate formula is used, even though there may be relevant symbols and applicable substitutions.
When an error is made during substitution into a correct formula, a mark will be awarded for the correct formula and for the correct substitutions, but no further marks will be given.
1.3 If no formula is given, but all substitutions are correct, a candidate will forfeit one mark.
1.4 No penalisation if zero substitutions are omitted in calculations where correct formula/principle is given correctly.
1.5 Mathematical manipulations and change of subject of appropriate formulae carry no marks, but if a candidate starts off with the correct formula and then changes the subject of the formula incorrectly, marks will be awarded for the formula and the correct substitutions. The mark for the incorrect numerical answer is forfeited.
1.6 Marks are only awarded for a formula if a calculation has been attempted, i.e. substitutions have been made or a numerical answer given.
1.7 Marks can only be allocated for substitutions when values are substituted into formulae and not when listed before a calculation starts.
1.8 All calculations, when not specified in the question, must be done to a minimum of TWO decimal places.
1.9 If a final answer to a calculation is correct, full marks will not automatically be awarded. Markers will always ensure that the correct/appropriate formula is used and that workings, including substitutions, are correct.
1.10 Questions where a series of calculations have to be made (e.g. a circuit diagram question) do not necessarily always have to follow the same order. FULL MARKS will be awarded provided it is a valid solution to the problem. However, any calculation that will not bring the candidate closer to the answer than the original data, will not count any marks.
2. UNITS
2.1 Candidates will only be penalised once for the repeated use of an incorrect unit within a question.
2.2 Units are only required in the final answer to a calculation. Eenhede word slegs in die finale antwoord op 'n vraag verlang.
2.3 Marks are only awarded for an answer, and not for a unit per se. Candidates will therefore forfeit the mark allocated for the answer in each of the following situations:
2.4 SI units must be used except in certain cases, e.g. V∙m-1instead of N∙C-1, and cm∙s-1or km∙h-1 instead of m∙s-1 where the question warrants this.
3. GENERAL
3.1 If one answer or calculation is required, but two given by the candidate, only the first one will be marked, irrespective of which one is correct. If two answers are required, only the first two will be marked, etc.
3.2 For marking purposes, alternative symbols (s, u, t, etc.) will also be accepted.
3.3 Separate compound units with a multiplication dot, not a full stop, for example, m·s -1. For marking purposes m.s-1and m/s will also be accepted.
4. POSITIVE MARKING
Positive marking regarding calculations will be followed in the following cases:
4.1 Subquestion to subquestion: When a certain variable is incorrectly calculated in one subquestion (e.g. 3.1) and needs to be substituted into another subquestion (3.2 or 3.3), full marks are to be awarded for the subsequent subquestions
4.2 Multi-step question in a subquestion: If the candidate has to calculate, for example, current in the first step and gets it wrong due to a substitution error, the mark for the substitution and the final answer will be forfeited.
5. NEGATIVE MARKING
Normally an incorrect answer cannot be correctly motivated if based on a conceptual mistake. If the candidate is therefore required to motivate in QUESTION 3.2 the answer given to QUESTION 3.1, and 3.1 is incorrect, no marks can be awarded for QUESTION 3.2. However, if the answer for e.g. QUESTION 3.1 is based on a calculation, the motivation for the incorrect answer in QUESTION 3.2 should be considered.
