Discussion forum. The best way to ask a short question about the course materials is via Ed Discussion, an online discussion forum where you can ask (and answer) questions.
Lab TAs. Undergraduate lab TAs are available to answer general computing questions in Lewis 121/122. They can assist you in debugging, provided you have first made a reasonable effort to identify the bug and isolate the problem. For non-debugging questions, use Ed Discussion or office hours.
Canvas. You can find links for Zoom office hours, electronic reserves of course materials, and recorded versions of precepts in Canvas.
Precept Assignment. The best way to get a spot in the precept of your choice is to regularly check the registrar's Course Offerings page and/or the listings on TigerHub. In our experience, more than a quarter of the total class enrollment changes precepts during shopping period. Dramatic unresolved scheduling concerns can be addressed to our course administrator Sue Giranda (sgiranda@princeton.edu). The course's teaching staff cannot manage precept assignments.
