The teenager quit school after her GCSE year in order to audition for the ITV show and has now confirmed she has no plans to return for her AS or A Level exams.
Lauren explained to Metro that she wanted to focus on making it as a singer now she's had a taste of the limelight.
She said: "I won't be going back to school. I wouldn't have done X Factor if I didn't want to win, but I don't think winning is everything. You don't need to win to have a career. I made it to the semi-finals and if I work hard it's going to be okay."
Well, she is right that you don't have to win X Factor to find success.
One Direction finished in third place on their year and are currently the biggest band in the world, while other non-winners to have achieved stardom and record sales include Ella Henderson, Olly Murs, JLS and Rebecca Ferguson.
Lauren, 17, spoke with Reveal back in September about her decision to quit school in order to focus on X Factor.
She said at the time: "If I'm honest, I'm not academic. It wasn't a massively hard decision. I'm quite a chancer and I take a lot of risks but it wasn't as hard a decision as I thought it was going to be."
Lauren finished in fourth place on X Factor during last weekend's semi final, losing out to Andrea Faustini in the sing off.
She had been mentored by judge Cheryl Fernandez-Versini throughout the process, and Cheryl's thrown her support behind Lauren and predicted she'll be a success.
Lauren will have plenty to occupy her at the start of next year as she'll be on the 'X Factor Live Tour', but as for the future, anything is possible.
"That's a conversation that I need to sit down and have with my management and the team around me now," she told us. "It's so hard to determine where to go from here and as a 17-year-old girl, I don't really know what goes on. I need to trust the people around me and listen to their opinions."
