A-Levels for Linguistics Help! Watch
Oxford (http://www.ox.ac.uk/admissions/under...uages_a_2.html) has a modern languages and linguistics degree with no essential subjects.
Edinburgh (http://www.ed.ac.uk/studying/undergr..._xml=index.php) also lists no essential subjects.
From this I am to infer that any linguistics degree will probably not require specific subjects; but nevertheless a foreign language and a science subject will be useful (mathematics may also be useful)
These A Levels sound good - a lot of universities will look positively on the fact that you've chosen quite a wide range of subjects. However, if you did want to rethink your subjects you might take a look at English Language as an A Level, which is often the most obvious gateway into Linguistics, although your foreign language choices may be equally as good. Also, it may sound odd but a less obvious choice is Mathematics - in my Oxford interview last year something which really helped me when the tutors wanted to discuss linguistics was my AS Level study of Maths - we spoke about the transferrable logical and analytical skills. But you should do just as well with good grades in your chosen subjects! Good luck
