Synonyms for the word "retest" include second chance, do-over, follow-up test, reassessment, and double-check. Each of these words describes the act of testing again but with a different tone or context. For instance, a second chance may imply an opportunity to redeem oneself, while reassessment may refer to a more thorough evaluation.
