Both ask for 70%: Sophia across all Challenges, Milestones and Touchstones, and StraighterLine to make your credits eligible for transfer. UPI Study's pass mark is 70 too, and its proctored final must be passed.
StraighterLine lists 10 hours of tutoring per course plus 24/7 on-demand tutoring. Sophia lists learner support by phone, email or online chat, and tutoring services. Both say course materials are included.
