About These Exercises

Conditionals are one of the most tested grammar topics in English exams — and one of the trickiest to master. They describe situations that depend on a condition being met: from real possibilities ("If it rains, I'll take an umbrella") to imaginary scenarios ("If I were rich, I'd travel the world") and past regrets ("If I had studied harder, I would have passed").

This section covers all major conditional types: zero, first, second, third, and mixed conditionals, plus wish/if only constructions. Each topic includes a clear lesson with structural formulas, usage notes, and common mistakes, followed by interactive exercises you can practise online or download as PDF worksheets.

Whether you're preparing for Cambridge FCE, IELTS, or simply want to sound more natural in conversation, these exercises will help you choose the right conditional every time.
