1. Should I use a question mark or a period?
I can't go today so would it work tomorrow( )
2. Is this correct?
I did WELL on the test.
NOT
I did GOOD on the test.
WELL=ADVERB OR ADJECTIVE
GOOD=ADJECTIVE
1. If you put a comma after "today" and a question mark at the end, it'll be fine.
2. Yes, you have it all correct. The word "well" is needed in that sentence.
1. In the first sentence, you should use a question mark ("?") instead of a period ("."). This is because the sentence is a question, indicated by the phrase "would it work tomorrow?" at the end. When writing a question, it is appropriate to use a question mark to indicate that the sentence requires an answer.
2. The second sentence is correct in terms of using "well" and "good" correctly. "Well" is an adverb that describes how the action of doing on the test was performed, while "good" is an adjective that describes the test itself. So, saying "I did well on the test" is the correct usage, indicating that you performed the action of doing in a satisfactory manner. On the other hand, saying "I did good on the test" would be incorrect because "good" is an adjective and is not suitable for describing the action of doing.
