Character evidence problems require two classifications: whose character is at issue and why the evidence is being offered. Propensity, impeachment, habit, and other-acts reasoning use different rules.
Practice in Testify →Identify the person whose character is offered and the trait being proved. Then ask whether the proponent is using character to show conduct in conformity or for another permitted purpose. If character is admissible, determine the allowed method of proof for that issue and stage of the case.
A frequent trap is treating evidence of prior misconduct as automatically inadmissible 'character evidence' even when offered for a nonpropensity purpose. Another is using specific acts where only reputation or opinion testimony is permitted.
Write 'who / trait / purpose / method' before choosing an answer. That four-part classification usually reveals which rule family controls.
Law school Evidence exams may ask you to discuss both a forbidden propensity use and an alternative nonpropensity use. Analyze each purpose separately and then address any limiting instruction or Rule 403 concern.
For bar review, practice character evidence beside impeachment because prior acts and convictions can appear under both doctrines but serve different purposes and use different admissibility tests.
