2 9705/32/O/N/22 © UCLES 2022 Section A Answer two questions from one of the Parts A, B or C. Part A – Product Design The instruction ‘discuss’ denotes that you should: • examine critically the issues raised by the question • explain and interpret these issues as appropriate • introduce evidence wherever possible to support conclusions of arguments. 1 Fig. 1.1 shows a candle holder to be used on a restaurant table. recess 2 deep Fig. 1.1 (a) State a suitable material for the candle holder of the type shown in Fig. 1.1 and give two reasons for your choice. [3] (b) Use sketches and notes to describe how you would make one candle holder in a school workshop. [9] (c) Explain the changes which may be necessary to the design, the manufacturing method used and the material selected, if 100 identical candle holders were required. Use sketches and notes to support your answer. [8] 2 Discuss how the manufacturing methods available and public opinion influence a designer when selecting materials for one of the following: • outdoor seating • drinking straws • shopping bags.

You should approach the design question of your choice in the following manner: Analysis Produce an analysis of the given situation/problem, which may be in written or graphical form. [5] Specification From the analysis produce a detailed written specification of the design requirements. Include at least five specification points other than those given in the question. [5] Exploration Use bold sketches and brief notes to show your exploration of ideas for a design solution, with reasons for selection.

You are to design an outdoor play area that will allow a child to experience different fun activities. Maximum space available is 5m × 5m. The play area must be: • arranged in different configurations for at least two play activities • suitable for use by children aged 4–10 years. [80] 11 Market traders who sell clothes need to store their products and display them to potential customers. You are to design a product that can store and display a range of clothing to allow customers to browse and select items. The product must be: • easily moved into position at the market and securely fixed when in place • easily assembled and disassembled. [80]

It shows the basis on which Examiners were instructed to award marks. It does not indicate the details of the discussions that took place at an Examiners’ meeting before marking began, which would have considered the acceptability of alternative answers. Mark schemes should be read in conjunction with the question paper and the Principal Examiner Report for Teachers. Cambridge International will not enter into discussions about these mark schemes. Cambridge International is publishing the mark schemes for the October/November 2022 series for most Cambridge IGCSE™, Cambridge International A and AS Level components and some Cambridge O Level components.

9705/32 Cambridge International A Level – Mark Scheme PUBLISHED October/November 2022 © UCLES 2022 Page 2 of 14 Generic Marking Principles These general marking principles must be applied by all examiners when marking candidate answers. They should be applied alongside the specific content of the mark scheme or generic level descriptors for a question. Each question paper and mark scheme will also comply with these marking principles. GENERIC MARKING PRINCIPLE 1: Marks must be awarded in line with: • the specific content of the mark scheme or the generic level descriptors for the question • the specific skills defined in the mark scheme or in the generic level descriptors for the question • the standard of response required by a candidate as exemplified by the standardisation scripts. GENERIC MARKING PRINCIPLE 2: Marks awarded are always whole marks (not half marks, or other fractions). GENERIC MARKING PRINCIPLE 3: Marks must be awarded positively: • marks are awarded for correct/valid answers, as defined in the mark scheme. However, credit is given for valid answers which go beyond the scope of the syllabus and mark scheme, referring to your Team Leader as appropriate • marks are awarded when candidates clearly demonstrate what they know and can do • marks are not deducted for errors • marks are not deducted for omissions • answers should only be judged on the quality of spelling, punctuation and grammar when these features are specifically assessed by the question as indicated by the mark scheme. The meaning, however, should be unambiguous. GENERIC MARKING PRINCIPLE 4: Rules must be applied consistently, e.g. in situations where candidates have not followed instructions or in the application of generic level descriptors.

9705/32 Cambridge International A Level – Mark Scheme PUBLISHED October/November 2022 © UCLES 2022 Page 3 of 14 GENERIC MARKING PRINCIPLE 5: Marks should be awarded using the full range of marks defined in the mark scheme for the question (however; the use of the full mark range may be limited according to the quality of the candidate responses seen). GENERIC MARKING PRINCIPLE 6: Marks awarded are based solely on the requirements as defined in the mark scheme. Marks should not be awarded with grade thresholds or grade descriptors in mind.
