- 'Shall' is used with the First person (Shall I, Shall We)
- 'Will' is used with the second and third person (Will he, Will they, Will it, Will you)
- We will study more use of shall, can, may in Modals
- Let always comes in the beginning of the sentence. Let is followed by an objective pronoun (Let him, Let them, Let us). It is never followed by a subjective pronoun (Let I, Let you, Let he; these are wrong)
