The DUNE Neutrino Interactions and Standard Model working group are pleased to bring you a series of classes, talks, and hands-on activities. We hope they will give you a gentle introduction to neutrino-interaction physics; how we study interactions; and how we evaluate the effects of uncertainties in our detectors, models and more. The school will be held online with all the materials available for self-study. Join in when you feel like it, skip when you don't - whatever works best for you!
