Common mistakes to avoid

1. I will to mistake ❌

After will, use the base form, with no to: I will mistake. Will never takes -s, and the verb after it has no -s either. Say she will mistake, not she wills mistake or she will mistakes.

2. I will can mistake ❌

Will is a modal verb (a helper verb like can, must or should). Two modal verbs cannot go together. Use will be able to for can: I will be able to mistake. Use will have to for must: I will have to mistake.

3. When I will arrive, I will call you ❌

After when, if, before, after and as soon as, use the Present Simple for the future, not will. Say When I arrive, I will call you. Will goes in the other part of the sentence.
