What educators are saying
I can’t say enough positive things about my experience with Edfinity. The feedback from students has been great. Edfinity provides an excellent alternative to profit-driven publisher products. Brian Abbott, Eastern Iowa Community Colleges
We’ve had a great experience with Edfinity. It is a nice interface for WeBWorK which we are already using for several courses. Simple enough with exactly the features we need. The Edfinity team is really good about communicating with us. Benjamin Wilson, Stevenson University
I am so grateful for Edfinity. It has been very user-friendly both for me and my students. It has allowed me to engage students far more than I could with other homework systems. Emilie Wiesner, Ithaca College
Edfinity makes it easy to focus on the mathematics instead of the interface. It allows me to focus on using WeBWorK problems without feeling like a low-level programmer. Frank Farris, Santa Clara University
The interface is fantastic. It lets us spend more time working with students. The team is very helpful and friendly. Matt Thomas, Ithaca College
Edfinity is very intuitive. My students use it for both homework and exams. Tech support is very responsive. Tien Chih, Montana State University Billings
Edfinity keeps the best part of WeBWorK - its engine - and delivers an intuitive user experience, a definite plus for teachers and students. Ravi Shankar, University of Oklahoma
I love how easy Edfinity is to use, and appreciate how quickly my questions have been addressed by the Edfinity team. My students have also had a good experience. I plan on continuing to use Edfinity in the future. Margaret Watts, Doane University
