Just like with the DBQ, the LEQ's grading rubric was recently (2017) updated and modified. As such, you're going to want to look over the new info below.
As you might have noticed by looking at the rubrics, the writing of the LEQ is VERY similar to the writing of the DBQ, sans the documents. As such, after watching the video and looking at the PowerPoint and rubric, mosey on over to the DBQ for more details.
