Number

Suppose I am writing about my test score:
1. I received a score of a "97".
2. I received a score of a 97.
3. I received a score of "97".
4. I received a score of 97.
5. I received a "97".
6. I received a 97.
7. I received "97".
8. I received 97.


When should I use an article and quotes?

4. I received.got a score/mark of 97.
8. I received/got 97(%).

These are the most natural to me.

If the test is graded on a letter-grade basis:
1. I received a grade of an "A".
2. I received a grade of an A.
3. I received a grade of "A".
4. I received a grade of A.
5. I received an "A".
6. I received an A.
7. I received "A".
8. I received A.

Would it still be 4 and 8 that are correct?

I'd use L " I received an 'A'/an A grade, a grade A.

Raw numbers don't need articles or quotes, but letter grade do?

It's simply to make things clearer. If I write, "I got 97", it is pretty clear that I am talking about a mark/percentage. If I write "I got an A", it may not be so clear..

If I write" I have just got my test back; I got an A", I probably woudn't bother with the quotes.
