The faculty has compiled a rather detailed explanation about what is and what is not allowed for a home exam. Most of this should be self-evident, but obviously it is better to be explicit about these things...
Here you can find the mandatory cover page of the exam, spelling this out, along with the first part of the first exam page where I provide some additional information. Make sure you read, and understand, all of this well before the exam -- and let me (or Jake) know if anything is unclear!
