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 mark scheme 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. ± Remember that many candidates are writing in a second language. Effective communication is more important than grammatical accuracy. ± Occasionally, a part of a question may require a calculation whose answer is required for subsequent parts. If an error is made in the first part then it should be penalized. However, if the incorrect answer is used correctly in subsequent parts then follow through marks should be awarded. Indicate this with “ECF” , error carried forward. ± Units should always be given where appropriate. Omission of units should only be penalized once. Indicate this by “U-1” at the first point it occurs. Ignore this, if marks for units are already specified in the markscheme. ± Do not penalize candidates for errors in significant figures, unless it is specifically referred to in the markscheme. – 5 – M05/4/BIOLO/HP2/ENG/TZ1/XX/M +
