Will vs Going to Exercises

Choosing between will and going to is one of the most important decisions when talking about the future in English. Use will for quick decisions made at the moment of speaking ("I'll have the chicken, please"), predictions based on opinion ("I think she'll enjoy the film"), promises ("I'll call you later"), and offers ("I'll help you with that"). Use going to for plans and intentions you decided before speaking ("I'm going to start a new job next month") and predictions based on present evidence ("Look — she's going to fall off that wall!").

The biggest source of confusion for learners is predictions, because both forms can make predictions — the difference is the basis. "It will rain tomorrow" is your personal belief, with no visible evidence. "It's going to rain" means you can see dark clouds right now. In everyday English, native speakers sometimes use both forms for predictions, but in exams the difference matters. A simple test: ask yourself "Did I decide this before or right now?" and "Can I see evidence?" Your answers will tell you which form to choose.
