JEPPE HIGH SCHOOL FOR BOYS GRADE 12: JUNE EXAM 2026
MEMORANDUM LIFE SCIENCES DEPARTMENT
PRINCIPLES RELATED TO MARKING LIFE SCIENCES
1. If more information than marks allocated is given stop marking when maximum
marks is reached and put a wavy line and 'max' in the right-hand margin.
2. If, for example, three reasons are required and five are given mark the first three
irrespective of whether all or some are correct/ incorrect.
3. If whole process is given when only a part of it is required read all and credit the
relevant part.
4. If comparisons are asked for but descriptions are given accept if the
differences/similarities are clear.
5. If tabulation is required but paragraphs are given candidates will lose marks for not
tabulating.
6. If diagrams are given with annotations when descriptions are required candidates
will lose marks.
7. If flow charts are given instead of descriptions candidates will lose marks.
8. If sequence is muddled and links do not make sense Where sequence and links
are correct, credit. Where sequence and links are incorrect, do not credit. If
sequence and links become correct again, resume credit.
9. Non-recognised abbreviations accept if first defined in answer. If not defined, do
not credit the unrecognised abbreviation but credit the rest of the answer if correct.
10. Wrong numbering. If answer fits into the correct sequence of questions but the
wrong number is given, it is acceptable.
11. If language used changes the intended meaning do not accept.
12. Spelling errors If recognisable, accept the answer, provided it does not
mean something else in Life Sciences or if it is out of context.
13. If common names are given in terminology accept, provided it was accepted at
the national memo discussion meeting.
14. If only the letter is asked for but only the name is given (and vice versa) do
not credit.–
15. If units are not given in measurements Candidates will lose marks. Marking
guidelines will allocate marks for units separately.
16. Be sensitive to the sense of an answer, which may be stated in a different way.
17. Caption all illustrations (diagrams, graphs, tables, etc.).
18. Code-switching of official languages (terms and concepts): A single word or two
that appear(s) in any official language other than the learners' assessment language
used to the greatest extent in his/her answers should be credited if it is correct. A
marker that is proficient in the relevant official language should be consulted. This is
applicable to all official languages.
19. No changes must be made to the memoranda. The provincial internal moderator
must be consulted, who in turn will consult with the national internal moderator (and
the Umalusi moderators where necessary).
