Logical test means a condition when evaluated by computer whose result/outcome is true or false, there is no third option, for example if a student secures more than 45 marks it is considered as pass otherwise fail.
In Excel a single IF function (IF(logical_test, value_if_true, value_if_false)) evaluate only one logical test at one time, if we have more than one conditions/logical tests, then we use AND function or OR function along with IF Function.

Returns the logical value TRUE. You can use this function when you want to return the value TRUE based on a condition. For example:
=IF(A1=1,TRUE())

=IF(A1=1,TRUE)
If the condition is met, Excel returns TRUE in both examples. If the condition is not met, Excel returns FALSE in both examples.
