Our pricing depends primarily on the time it takes us to create each product ⏳. It is not based on the number of pages, problems, or illustrations.

We estimate the total number of hours required to produce high-quality notes and materials, multiply that by a fair baseline wage, and then divide it by the expected number of students who will benefit from the product.

Our pricing is designed to be accessible to students while reflecting the real work required to create high-quality materials 📚. We are committed to offering high-quality courses and notes at an affordable price for students 🎓.
