How about some vocabulary quizzes? I think they will suit you quite well… Just to break the grammar monotony 😀

I think you’ve had enough time to finish the Present Simple exercises I gave you, so here’s Present Continuous. Have fun!! 🙂 You have a small quiz at the end, too!
Keep calm and learn English!! 😀
