It is a fact: we love numbers, statistics, percentages... And our English level is no exception.Since the European Union decided on the new terminology to grade level of competence in a language (from every basic to very advanced: A1-A2-B1-B2-C1-C2 ), European tests have adapted to this terminology.
Obviously this is business and money for academies, publishers, course writers, etc.
Here is a free website by Cambridge to have a quick (only 25 questions) international on-line test placement. Apart from that, here is another more accurate and comprehensive test. The second test will take you 30 minutes and the results are instant. Wanna try it??
