Well, instead of talking about what grammar points are currently taught, I will look at grammar that is regularly taught. Well when students get into the pre-intermediate levels,we start introducing more complex grammar structures like Verb tenses, Present perfect vs. Past simple, Future forms, Comparatives and superlatives. We also usually introduce some modals here like the modal "Should" for giving advice. We bring in useful communicative lexical chunks alongside key grammar features like modals for polite expressions.
