How hard is A level Computer Science without the gcse Would it be too difficult to take a level cs without the GCSE?. It’s OCR by the way . Do they recap the GCSE . Please help 🙏

I am thinking of picking cs along with math and chemistry . I have picked cs as I am interested in computers and stuff like that and I want to know if they recap the GCSEs at the start of the course . If not I might not pick it
