Mark scheme for Topic 1 Exam-style topic test
General information
The following symbols are used in the mark schemes for all questions.
; semicolon ­ indicates the end of a marking point.
eq ­ indicates that credit should be given for other correct alternatives to a word or
statement.
/ oblique ­ words or phrases separated by an oblique are alternatives to each other.
{ } ­ indicate the beginning and end of a list of alternatives (separated by obliques)
where necessary to avoid confusion.
( ) ­ words in round brackets are not required to award the point.
Crossed out work should be marked UNLESS the candidate has replaced it with an alternative
response.
In general, an error made in an early part of a question is penalised when it occurs but
not subsequently. The candidate is penalised once only and can gain credit in later parts
of the question for correct reasoning from the earlier incorrect answer.
The spelling of technical words must be sufficiently correct to be unambiguous, e.g. for
mitosis, mytosis would be acceptable whereas meitosis would not.
The meaning of an answer must be clear to gain the marks.
A correct statement that is contradicted by an incorrect statement in the same part of an
answer gains no mark.
