OCR GCSE 21st Century Additional Science – J631

OCR GCSE 21st century Additional Science – J631

[box type=”note”]Note: these are details for the OLD Additional Science course. If you are currently doing additional science after having taken core science last year, then you’ll almost certainly be following this old course, unless you’re in year 10 and going for triple science. Check the OCR website for details of the new course.  CHECK with your teacher or exams officer just to make sure. [/box]

As usual for science gcses there are four modules – three examined by written exams and one by contolled assessment. Each counts for 25% of the total marks. The controlled assessment module comprises a Practical Data Analysis and Case Study of a topical issue in science from a choice set by OCR Assessed by teachers, internally standardised and externally moderated by OCR.

Here is a link to the specification.

Course Content

There are three modules for each of Biology, Chemistry and Physics, just like for Core Science A.


Module B4: Homeostasis
