Greetings all, I recently wrote a midterm exam for my physics laboratory class using Latex. In preparing the document, I used some latex packages (specifically circuitikz). I want to post my .tex file and a pdf on my github page for students in future classes to view as a sample exam or anyone else that may be interested (educators etc.). I was wondering what license I should post this document under? Or should it even have a license? For the record, I don't care who or how someone uses it. Thanks ahead of time.
