同埋GCSE係一定要有science,所以正常學生無可能會出現「GCSE冇讀過science」嘅問題
Which GCSE options are compulsory?
Maths, English and Science are the core subjects everyone must take at GCSE in England. English Language is compulsory in all schools, and so is English Literature in the majority of schools, but there are exceptions, so do check.
Science may be split into the three separate sciences (Biology, Chemistry and Physics) or into two combined Science GCSEs.
