Personally I think the main problem was lack of commitment in customer discovery and how much were you paying the PHD students? Why weren't they motivated enough to help you advertise? In the US, most graduate students assist professors in teaching classes, so they would have direct contact with the people who would want your services the most. What was your motivation for your startup? Did you just want to make a buck, or did you really care about helping students do better in their exams? Do you think the decisions you made would have been different if you had different motivations?
