It's always a good idea to have objectives when you are learning a language, and preparing for and taking an official exam can be a good way to provide extrinsic motivation. The exam I'm most familiar with is the TOEIC (Test of English for International Communication), since all EM Normandie students have to achieve a minimum score of 750 (out of 990) to graduate. Over the years, I've put together an extensive list of TOEIC resources, and I'm pleased to be able to share them with you here.
