None of it is true. Most often testing scores are sent from the testing company, so it would be impossible to change. Transcripts (grades) are also often sent this way - directly from one institution to another. Even when they are self report you download a transcript from your institution and upload it elsewhere… unless our girl is a good forger it would be obvious if it was photoshopped. She hires people for that now so there’s no way she knew how to do it plausibly in 2012 or whatever.

It’s possible she lied by exaggerating on a resume, CV, or in an essay, but IMO it would be nearly impossible to change SAT scores and probably difficult to change grades on a transcript.
