what do you mean that they are the dynamics? i was under the impression that the dynamics are things like originality, experimentation, cleverness +joys of invention, conversations between and among texts.... from the rubric? is that what everyone has been taught??
bad idea though unless the analysis is amazing. even if one of your related texts is in the unseens you should have at least one back up... our school makes us prepare 4 relateds altogether in case that happens.
