AND is a logical used to test Boolean expression and it will return TRUE if both Expr1 and Expr2 are TRUE, else it returns FALSE.

For example, suppose you want to promote students in Form 3 whose Marks is greater or equals to 350, then write the expression shown:
(Form=3 AND marks>=350)

Note that: You only quote string expression(s) but not values.
