Raffles Institution Physics Department H2 Physics 97 49/ Paper 4 (Practical) The following revision notes apply to Prelim and A-Level Practical. Format of paper: Total duration Wei 2 hr 30 min A-Level format for reference : o 1 st hour : either 1 long or 2 short experiments o 2 nd hour: change over to the other experiment/s Marks 55 o Last½ hour: Planning question (cannot touch apparatus during this last 30 min or you will be penalised ! ) In 2021 : In 2022: The short questions were 01 [10 marks] and 02 [11 marks].
