Original poster's comment: 

It pains me to report this, but the AP English Literature scores this year are the lowest they’ve been this decade.
Multiple-choice: students scored better on 20th century texts and prose, than poetry and pre-20th century texts.
Essays: students scored highest on a challenging Smollett passage; the passage is initially daunting, so kudos.
Essays: students scored lowest on Harper’s poem but some readers mentioned great essays recognizing parallels to jazz improv.
