Define the logical requirement in words

An IF formula can evaluate several conditions by combining its logical test with AND or OR. The source explains that AND requires every stated condition to be true, whereas OR succeeds when at least one condition is met. That distinction should be settled before writing the expression. A result that requires two qualifying scores is a different rule from one that accepts either score, even if the surrounding spreadsheet looks identical.

Keep the returned outcomes explicit

The logical test determines which of IF's two outcomes is returned. The article illustrates this with an AND test requiring both values to exceed a threshold before producing a passing result. Start with a small example and confirm the expected true and false cases. Adding more conditions does not make a formula more accurate unless the relationship between them represents the actual business rule being applied to the data.
