I like how students who understand the material can get through the homework quickly and students who need more practice get it. The fact the materials used are OER fits into the philosophy of my college. The overall cost to students is quite reasonable. And I love the integration of DESMOS with the homework and student instructional assistance. Review collected by and hosted on G2.com.

It is not always as clear what needs to be taught for each section unless you manually review each homework section's instruction. The OpenStax book for Statistics is not very robust, but Alta gets around that by supplementing with more materials (that are still open source). Review collected by and hosted on G2.com.
