Why would you even think that?
“Wendy, will you marry me?”
“Well, John, you know that I love you and that you are a great guy, but I couldn’t ever marry a man who got a C in English Lit in High school”.
“Hi. I’m James, and I couldn’t help noticing you, would you have a coffee with me, but first, I need to know, what was your Pre-Calc grade in your Sophomore year?”
“Ummm C, I think”
“Sorry, I thought you were somebody else”.
“Dave, I don’t know what to do, he’s good looking, he’s funny, he has a well thought out plan for the future, and he loves me”
“So what’s the problem?”
“He got three B’s in his Junior Year in HS”
“I cannot believe that you even dated him, much less that you’re thinking of marrying him!”
So, no, your future in-laws won’t ask for your HS transcripts.
Once you finish your undergraduate, nobody will ever ask to see your HS grades ever again. Well, if an employer asks for them, you may want to find a different place to work.
If a potential spouse or their family cares about your HS grades, a D in Honors Physics is the least of the problems in that relationship.
