Ms. Sardelis said we must "absolutely and without delay" turn in our permission slips by tomorrow or we can't go on the class trip.

is this correct

As long as the words in the quotation marks are the exact words she said, then it's fine. If it's a paraphrase of what she said (not a quote), then remove the quotation marks.

This lady is incorrect! my online Plato course asked this exact question, and said that the punctuation was wrong

To determine if Ms. Sardelis' statement is correct, we need to examine the information provided. Ms. Sardelis stated that the permission slips must be turned in "absolutely and without delay" by tomorrow, or else the students cannot go on the class trip.

In this case, the correctness of the statement depends on whether it is in line with the school's guidelines or policy regarding permission slips and class trips. It is essential to consult the school's policies or communicate directly with Ms. Sardelis or the school administration to obtain accurate information regarding the deadline for turning in the permission slips. They will have the final say on whether the statement is correct or not.

To clarify the situation, I would recommend reaching out to Ms. Sardelis or the school administration to confirm the deadline for submitting the permission slips and clarify any doubts or concerns you may have.
