There has been a GCSE in Biblical Hebrew available from OCR for some time. In the recent overhaul of GCSEs the exam was withdrawn by OCR. The exam has now been taken up by Edexcel and the first exam is available in 2020.
Don't be put off by the sound of Biblical Hebrew - it is not a very difficult language to learn and the exam looks accessible if you have reached the required language standard. There is no coursework. The exam is two papers.
Past papers are still available (lots of them) through OCR.
