BitLife's Graduate School Guide
To graduate from a Graduate School, you must maintain a good smarts stat over 90 throughout your lifetime. After joining a school, use the Study Harder option yearly from the Activities tab to increase the smarts parameter. Along with that, visit the Library or join a debate club to keep your mind sharp during your school days.
After graduating from high school, it's time to join a college. While navigating the list of available courses in a college, you may also choose to use the same Study Harder option in university. Go to the careers tab and select the Graduate School option. You will be permitted to start Graduate School if you have maintained the smart stat over 90.
