Common mistakes to avoid
1. I will to agree ❌
After will, use the base form, with no to: I will agree. Will never takes -s, and the verb after it has no -s either. Say she will agree, not she wills agree or she will agrees.
2. I will can agree ❌
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 agree. Use will have to for must: I will have to agree.
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.
