American and French school systems differ greatly. American students attend kindergarten for one year, have more lenient grading on a 100% scale, participate in many extracurricular activities, and typically have less than two hours of homework per night. French students are in kindergarten for three years, receive tougher grades on a 20-point scale, focus only on academics, and have four to six hours of homework each night. Overall, the French system appears more rigorous and stressful for students.
