GCSE in Combined Science

Board: OCR
Syllabus Code: J250

This option offers an alternative to studying separate GCSEs in Biology, Chemistry and Physics. The specification is divided into topics each covering different key concepts of science. Teaching of practical skills is integrated within the course. Successful completion leads to the award of two GCSEs. This course is most suited to candidates that want a broad appreciation of all three science disciplines but with a slightly reduced content compared to the separate science subjects. Therefore, it is still an excellent preparation to study any of the Sciences at A Level or within the International Baccalaureate Diploma, but student use one less option slot compared to students that study all three sciences separately at GCSE. Read the OCR full specification.


Each science subject is assessed by terminal examination with two papers per subject (6 examination papers in total). Each paper is seventy minutes long and worth 60 marks. Paper one assesses the first three teaching topics and paper two examines the others, with an assumed knowledge of topics one to three (for details of topics see table below).
