Following a discussion at parent's evening last night I have included in this section a few adresses of Specialist language bookshops in London.
The textbook that we use in class is called "Metro" but do not feel obliged to purchase this textbook. There are a lot of cheaper resources available in these bookshops as well as online (as discussed your son can use this website and all the MFL links to revise his vocabulary.
Grant and Cutler, 55-57 Great Marlborough Street, W1, 020 7734 2012 www.grantandcutler.com
The European Bookshop, 5 Warwick Street, London W1B 5LU, 020 7734 5259 http://www.europeanbookshop.com/
Also if you fancy a trip to south Kensington you can stop at the French Institute "L'institut Francais". They have a lage library and a lot of media resources.
