Did you get A on English Exam --- Is this expression correct?

No, the expression "Did you get A on English Exam" is not entirely correct. Here's why and how to fix it:

* Article: You need an indefinite article ("an") before "A" because "A" is a vowel sound.

* Capitalization: "English Exam" should be "English exam" unless it's the name of a specific exam (like the "Advanced Placement English Exam").

The corrected sentence is: Did you get an A on the English exam?
