OCR Gateway Additional Science – J262

OCR GCSE Gateway Additional Science – (J262)

There are two modules for each science – Biology B3 and B4, Chemistry C3 and C4 and Physics P3 and P4, leading on from the core science modules. These modules are assessed by two exam papers counting together for 75% of the total marks.

As usual, there is a controlled assessment (practical) which accounts for the remaining 25% of the total marks.
