The U.K. resident named Victoria Mario set up a GoFundMe page requesting £40,000 which is roughly $53,000.
Swift, 30, donated on Thursday £23,373, which equates to around $30,000.
“Victoria, I came across your story online and I am so inspired by your drive and dedication to turn your dreams into reality,” the “Cardigan” singer wrote on the GoFundMe page.
She added: “I want to give you the rest of your goal amount and good luck with everything you do! Love, Taylor.”
Mario, 18, was accepted to the prestigious Warwick University for a degree in mathematics but said her family is “low income, and unable to help me self-fund through university.”
She described herself as a “Black woman with a dream” and explained her immigration story from Portugal in 2016 when she was “unable to utter a word in English.” “It was a sacrifice worth being made,” she said of moving without her mother to get a better education.
“Though my story is not unique, my dream of becoming a Mathematician is not only a chance at social mobility for my family and I, but to inspire people who have been in similar positions to aspire to be the best version of themselves and strive for their dreams despite gender/racial inequality, immigration issues and financial barriers,” Mario concluded.
A week before Swift’s donation, she proudly updated the page and said, “MY PLACE AT WARWICK HAS BEEN CONFIRMED.”
The U.K. resident still had a significant amount of money to raise by then and the pop star’s donation let her reach her financial fundraising goals. She has since surpassed her initial request.
In an interview with BBC Radio London, Mario vowed "to make Taylor proud".
"I didn't know what to do. Even the message was really nice,” she said of Swift.
The 18-year-old added: "I don't know how [Swift] saw it. If it was someone from the U.K. I would be less surprised."
Mario also admitted she was already a fan of Swift, but will now be a fan "for the rest of my life.” She added, "I want to thank her with all my heart."
