The extra information is aligned to the appropriate answer in the left- hand part of the mark scheme and should only be applied to that item in the mark scheme. At the beginning of a part of a question a reminder may be given, for example: where consequential marking needs to be considered in a calculation; or the answer may be on the diagram or at a different place on the BIOLOGY 1102 BIOLOGY PAPER 1 MS 2023/2024 RATED A+ BIOLOGY 1102 BIOLOGY PAPER 1 MS 2023/2024 RATED A+ BIOLOGY 1102 BIOLOGY PAPER 1 MS 2023/2024 RATED A+ BIOLOGY 1102 BIOLOGY PAPER 1 MS 2023/2024 RATED A+ *206g8464b1H/MS* BIOLOGY 1102 BIOLOGY PAPER 1 MS 2023/2024 RATED A+ BIOLOGY 1102 BIOLOGY PAPER 1 MS 2023/2024 RATED A+ BIOLOGY 1102 BIOLOGY PAPER 1 MS 2022/2023 RATED A+ BIOLOGY 1102 BIOLOGY PAPER 1 MS 2022/2023 RATED A+ Name two planets in the solar system. [1 mark] Studen t Response Marks awarde d 1 Neptune, Mars, Moon 1 2 Neptune, Sun, Mars, Moon 0 3.2 Use of chemical symbols / formulae [2 marks] 1 If a student writes a chemical symbol / formula instead of a required chemical name, full credit can be given if the symbol / formula is correct and if, in the context of the question, such action is appropriate. 3.3 Marking procedure for calculations Marks should be awarded for each stage of the calculation completed correctly, as students are instructed to show their working. Full marks can, however, be given for a correct numerical answer, without any working shown. 3.4 Interpretation of ‘it’ Answers using the word ‘it’ should be given credit only if it is clear that the ‘it’ refers to the correct subject. 1 3.5 Errors carried forward In the mark scheme additional information, ‘allow’ is used to indicate creditworthy alternative answers. 3.9 Ignore Ignore is used when the information given is irrelevant to the question or not enough to gain the marking point. Any further correct amplification could gain the marking point. 3.10 Do not accept Do not accept means that this is a wrong answer which, even if the correct answer is given as well, will still mean that the mark is not awarded. 4. Level of response marking instructions Extended response questions are marked on level of response mark schemes. • Level of response mark schemes are broken down into levels, each of which has a descriptor. • The descriptor for the level shows the average performance for the level. • There are two marks in each level. Before you apply the mark scheme to a student’s answer, read through the answer and annotate it (as instructed) to show the qualities that are being looked for. You can then apply the mark scheme. Step 1: Determine a level Start at the lowest level of the mark scheme and use it as a ladder to see whether the answer meets the descriptor for that level. The descriptor for the level indicates the different qualities that might be seen in the student’s answer for that level. If it meets the lowest level then go to the next one and decide if it meets this level, and so on, until you have a match between the level descriptor and the mark scheme. You should ignore any irrelevant points made. However, full marks can be awarded only if there are no incorrect statements that contradict a correct response. An answer which contains nothing of relevance to the question must be awarded no marks. BIOLOGY 1102 BIOLOGY PAPER 1 MS 2023/2024 RATED A+ Ques ti on Answers Extra information Ma r k AO / Spec .
