Here are some resources to help introduce you to Beowulf. Please read/listen/read some more, then answer the comprehension questions at the bottom of the post. [*You may want to read these first.]
The Norton Anthology of English Literature is an outstanding reference work. We don't have copies, so I am embedding pieces here.
First, an introduction that provides some historical context.

The best beginning procedure is always to read the assignment all the way through, keeping track of characters, so that you know what's happening. If possible, read the whole work first. Try to get the
big picture of the book (or section, or chapter) before getting bogged down in details. Read through, then go back and clear up details. Then you're ready to read the work closely with these questions in mind. (In the discussion below, page numbers in parentheses refer to the translation by Seamus Heaney in The Norton Anthology of English Literature, 7th ed., vol. 1  unless otherwise indicated.)
