– 3 – N05/4/BIOLO/HP2/ENG/TZ0/XX/M+ General Marking Instructions Subject Details: Biology HL Paper 2 Markscheme Mark Allocation Candidates are required to answer ALL questions in Section A total [32 marks] and any TWO questions in Section B [20 marks] each. Maximum total = [72 marks] . General A markscheme often has more specific points worthy of a mark than the total allows. This is intentional. Do not award more than the maximum marks allowed for part of a question. When deciding upon alternative answers by candidates to those given in the markscheme, consider the following points: ± Each marking point has a separate line and the end is signified by means of a semicolon (;). ± An alternative answer or wording is indicated in the markscheme by a “/”; either wording can be accepted. ± Words in (…) in the markscheme are not necessary to gain the mark. ± The order of points does not have to be as written (unless stated otherwise). ± If the candidate’s answer has the same “meaning” or can be clearly interpreted as being the same as that in the markscheme then award the mark. ± Mark positively. Give candidates credit for what they have achieved, and for what they have got correct, rather than penalising them for what they have not achieved or what they have got wrong. ± Occasionally, a part of a question may require a calculation whose answer is required for subsequent parts. ± Units should always be given where appropriate. Omission of units should only be penalized once. ± Do not penalize candidates for errors in significant figures, unless it is specifically referred to in the markscheme.

– 4 – N05/4/BIOLO/HP2/ENG/TZ0/XX/M+ Section B Extended response questions - quality of construction ± Extended response questions for HL P2 carry a mark total of [20] . Of these marks, [18] are awarded for content and [2] for the quality of construction of the answer. ± Two aspects are considered: expression of relevant ideas with clarity structure of the answers. ± [1] quality mark is to be awarded when the candidate satisfies EACH of the following criteria. Thus [2] quality marks are awarded when a candidate satisfies BOTH criteria. Clarity of expression : The candidate has made a serious and full attempt to answer all parts of the question and the answers are expressed clearly enough to be understood with little or no re-reading.
