Edger Allen Poe's Poem The Raven?

Recentally I have been igned the poem The Raven by Edger Allen Poe. I am supposed to read the poem and answer 10 questions that my teacher gave me. I do not understand the poem at all. I have asked for help, I have read it aloud, read it over, i've done everything. Normally I am a very good reader, (College reading level in 8th grade) but I just really do not understand The Raven. Could I have some help knowing or figuring out the meaning of the poem?
