What is the correct phrase to use in the sentence: You _________ on your final exam?

The phrase "did well" is the correct choice to complete the sentence "You _________ on your final exam" because it appropriately conveys a positive outcome regarding performance. The phrase uses the simple past tense "did" along with the adverb "well," which effectively describes the manner in which the exam was taken.

In this context, "did well" is a common expression that implies the person performed satisfactorily or successfully on the exam, aligning with the expected way to assess and communicate exam results in English.

The other options do not fit the context as effectively. "Worked" suggests effort but does not indicate the outcome related to the exam. "Forget" is grammatically incomplete in this context and does not fit the intended meaning. "Done good" is an incorrect grammatical construction; the proper form should be "done well," as "good" is an adjective and cannot be used as an adverb in this context. Therefore, "did well" is the most appropriate and grammatically correct choice.
