It's a short grammar test with exercises on Present Simple, Present Continuous, Simple Future and be going to. There's also an exercise checking their knowledge of the time words used with these tenses and of course my favourite written speech production exercise a.k.a make your own sentences using the words given. I always give my students tests like this checking their understanding of the grammar they have been taught. Make sure they practise enough before assigning the test! There is no key included.
