This document introduces an e-learning network in mathematics across universities in Saxony, Germany. The network shares electronic assessments created using ONYX and MAXIMA. Over 50 authors have created more than 1000 assessment questions across various math topics. The assessments provide interactive practice and feedback for students and inform instructors. OPAL is the learning platform where assessments are hosted, accessible to 80,000 university members. ONYX allows various question types and MAXIMA can analyze student responses with random parameters and math expressions as answers. The speaker's university courses use the assessments, with around 200 students taking 4 timed tests worth bonus points.

7. My magic moment
The network and the ONYX-Assessment tool have been a chance to
establish electronic assessments which offer two essential benefits:
1 interactive training and feedback for the students
2 feedback for the lecturers
