Level 2 is different from Level 1 in a few ways. Most simply, Level 1 teaches the persuasive essay and introduces the comparison essay while Level 2 divides the persuasive essay into the judicial (to do with the past tense) and the deliberative essay (to do with the future tense). Level 2 also includes a four lesson unit on story-telling and it develops the comparison essay further. And, finally, it adds a descriptive essay.
Level 2 also adds to additional topics of invention: the advantageous and the honorable. It also adds 12 new schemes and tropes.
