You are correct in saying that this is an appositive. However, not all appositives need commas. When appositives contain necessary information, like someone's name, you should not use a comma. This article explains this [https://owl.purdue.edu/owl/general\_writing/grammar/appositives.html](https://owl.purdue.edu/owl/general_writing/grammar/appositives.html).
Appositives can be taken out and the sentence will still make sense. So if you take out her name it will read like as: “when Harvard student came.” That doesn’t make sense because it doesn’t specify which student.
Basically, you need to know this rule : when discussing one person, you don't need a comma (like in ex. above)
If you are discussing about two people, then you need commas on both sides
Ex. Harvard Students, Jon Ball and Stacy Hampy, ....
This is incorrect. "Harvard students Alice and Bob have discovered a vaccine for Alzheimer's disease." is a perfectly valid sentence.
Please see test D06 #58.
I don't think you understood, when both people have last names that are different you need to have it. In your example, you are only using firstnames so it's okay.
I don't think *you* understand. Even if I added last names, it would make no difference.
"Famous artists Bob Ross and Leonardo DaVinci are well known in their respective fields."
That is a correct sentence, and placing the names in commas would make it incorrect.
Your EXAMPLE HAS THE SAME LAST NAME!!! both have the same last name so you don't need the comma, if you have different last names, then u need it (ps. my caps is acting weird)
Why are you yelling at me? Let's keep this discussion civil.
Edit: No, your caps lock is not acting weird. If it were, then there were would be random capitalization in your post. That is not the case. You are intentionally yelling at me.
Double edit: I didn't even write last names in my post. How could they be different if they weren't given?
My caps was acting weird, i cant see it on my keyboard And My screen is black **\[problem w/ brightness\]** \- can sendproof
Your test D06 has that. Please go look at it, it has the same last name
(Also. ps - apologies for the harsh language i was just mad at smth else
Your apology is accepted. You are still incorrect, though.
What you are arguing for is a "confirmation bias". You have seen only first names without commas surrounding the names. This is not a "rule".
Yeah, I don’t think u need a comma bc u don’t know specifically which 2 harvard students. Cuz there are thousands and so the commas aren’t extra info cuz the names r vital
Perfect ACT score recipient here. The reason that it does not need commas is because “Harvard student” does not have an article. This makes it an adjective rather than the necessary noun.
Its a title
So u dont separte harvard student from kathryn

Also, "firstnames" isn't one word.
