Build accurate meaning as well as accurate reading
A useful vocabulary review connects a written form, a reading and an example that makes the meaning clear. When a character has several readings, learn the whole word rather than choosing a reading from a different compound. Homophones require semantic context: interest in a subject and admiration for an effort are not the same relationship even when both are pronounced かんしん. For a compound's structure, distinguish similar meanings, opposing meanings, a modifier and an action followed by its object. Do not mistake an imaginative story about a character's shape for a supported etymology. Idioms and proverbs need their conventional figurative meaning, but a complete sentence still determines how that meaning applies. In review, write the reason a tempting distractor fails rather than copying the correct pronunciation alone. Build a small group of contrasting examples, then test whether you can select and explain the appropriate word in a new context without relying on the order of the choices.
