Goodbye, PUA: Reborn, I’m Working Hard to Get into College

An Unexaggerated Story About Someone Reborn Before the College Entrance Exam and Starting a Business in College

Are there any novels where the protagonist is reborn in high school, goes to university after the college entrance exams, and starts a business in college, preferably in the internet industry? I'd like the story to focus mainly on university life and the startup journey. It should feel realistic, with a good plot that isn't over the top. Thanks!
