Final answer:
Online learning offers flexibility with schedules, access to courses not available at one's school, and the opportunity to recover credits after failing a course.
Step-by-step explanation:
According to the source material provided, the benefits of online learning include the flexibility for students to take classes that do not fit in their schedules and the opportunity to enroll in classes that their schools do not offer. Also, it allows students to recover credits if they fail a course, which can be crucial for staying on track with their education. However, the source does not mention that students do not have to earn high school credits, nor does it support the idea that students can make friends more easily through online learning.
