Grammar review
At C1-C2 level, conditionals go beyond grammar formulas and become tools for expressing complex reasoning. You might see sentences like: "Were it possible to turn back time, I would not have made that decision, and we would be in a very different position today" — combining inverted second conditional, third conditional, and mixed conditional in one sentence. This exercise pushes your understanding of how conditionals function as a system rather than as isolated structures. Success here demonstrates the grammatical range and accuracy expected in Cambridge C1 Advanced and C2 Proficiency exams, as well as IELTS band 8+ academic writing.
