ESL Activities for B2 (Upper-Intermediate) Students
Every ENK game calibrated to CEFR B2, with what it actually asks a B2 student to say — free to browse, no login required.
B2 has the widest calibrated coverage of any level on the platform — 24 of ENK's 26 apps — because it's where a learner can finally do the things a lot of classroom speaking practice actually wants: explain the consequences of a decision, describe a problem and how it got resolved, argue for or against a genuinely complex position, and narrate an anecdote with real cause-and-effect structure. The grammar underneath that is substantial: second and third conditionals, passive voice across tenses, modals of deduction and obligation (must have, should have, would have), mixed conditionals, and complex noun phrases built on relative clauses.
This is also the entry point for ENK's Cambridge Preparation apps (B2 First format), which is why the jump in app count between B1 and B2 is real rather than an artifact of rounding.
