Do university admissions reject a native language as 3rd A level?Watch
My daughter is taking Bio Chem and possibly German as her third A level. She is German by nationality but living in the UK and studied in the German School and now doing A levels.
Therefore if you are a native speaker, or your parents are so it is a language used at home, then you have a substantial advantage in the exam.
For highly competitive universities, for whom the ability to handle the workload of 3 full A levels is a significant predictor, have a 'home advantage' in one A level can be seen as a disadvantage, ie lack of evidence. Universities with less demanding academic entry requirements may be fine with it.
Unis are discouraged from doing so because it’s actually a bit prejudice to make assumptions about someone’s language skills based on their address, nationality etc. After all, there’s nothing to stop a British national being bought up in a bilingual household having an advantage over a German national who in fact was brought up in a in English speaking one.
However, there’s nothing to stop unis excluding language qualifications in general if they don’t think it’s suitable prep for their course.
Long story short: Check before applying and assume nothing.
General advice for anything admissions related that you’re not sure about: check the university course webpage or contact admissions directly.
