>made it halfway through university with Bs never studying ever in my life
>start heading towards C range with calc 1, gen chem
>realize I'm gonna have to learn to study if I want to survive in STEM
>put in like ten total hours before calc II midterm just got a 99%, best grade I ever got on anything since middle school
