2024-DSE-PHY 1B–2 HKDSE Physics General Marking Instruction 1. It is very important that all markers should adhere as closely as possible to the marking scheme. In many cases, however, candidates may have obtained a correct answer by an alternative method not specified in the marking scheme. In general, a correct answer merits the answer mark allocated to that part, unless a particular method has been specified in the question. Markers should be patient in marking alternative solutions not specified in the marking scheme. 2. In the marking scheme, answer marks or ‘A’ marks are awarded for a correct numerical answer with a unit. In case the same unit involved is given incorrectly for more than once in the same question, the ‘A’ marks thereafter can be awarded even for correct numerical answers without units. If the answer should be in km, then cm and m are considered to be wrong units. 3. In a question consisting of several parts each depending on the previous parts, marks for correct method or substitution are awarded to steps or methods correctly deduced from previous answers, even if these answers are erroneous or for inserting values of appropriate physical quantities into an algebraic expression irrespective of their order of magnitudes. However, ‘A’ marks for the corresponding answers should NOT be awarded (unless otherwise specified). 4. For the convenience of markers, the marking scheme is written as detailed as possible. However, it is still likely that candidates would not present their solution in the same explicit manner, e.g. some steps would either be omitted or stated implicitly. In such cases, markers should exercise their discretion in marking candidates’ work. In general, marks for a certain step should be awarded if candidates’ solution indicated that the relevant concept/technique had been used. 5. In cases where a candidate answers more questions than required, the answers to all questions should be marked. However, the excess answer(s) receiving the lowest score(s) will be disregarded in the calculation of the final mark. 6.
