there are still a couple of weeks to go before September exams so I thought you could use some exercises.

I recommend this test for checking your knowledge of British vs American English. It's fun and you only have 5 minutes to do it. You can play it again and again until you manage to complete the list within the allotted time :-)
enjoy your holidays
