OK after a long, long night here are my suggested answers for the Combined Science (Physics, Chemistry) 5116 and (Physics, Biology) 5117 MCQ Paper 1 (along with the usual workings, diagrams and explanations).
Those of you taking other combinations (e.g. Chemistry/Biology 5118) in this ‘O’ Level should probably encounter the same set of 20 Physics or 20 Chemistry or 20 Biology MCQs.
Hope the explanations will clear up some doubts in the
argument discussion with your friends on whether it’s “B or C” or “A or B or C or D” (?!) Once again, please leave a comment if you spot any mistake, typo and/or wish to clarify any of the explanations given.
All of you should be rejoicing now in your new-found freedom. Unfortunately not for me though *looks over shoulder at my sister*
