Depending on your college major and courses, I recommend taking at least one of the actuarial exams while still in college if possible. This is easier if your classes match up well with an exam (if you're in an Actuarial Science program and taking a probability course, for example), but it is very possible to study and pass on your own. Passing at least one exam opens the door for more internships while you're still in college, which makes it easier to find a full time job when you graduate. The first few exams are the same regardless of your job, so you don't need to choose a path (life/health vs. property/casualty) until later.
I don't believe additional schooling is necessary beyond a bachelor's (in anything); passing actuarial exams is much more important for starting the career. Most employers of actuaries will support continuing taking exams while working full time with paid days off to study, paying for study materials and classes, and paying for the exam fees themselves.
