Ah. From what you'd said, I thought you needed to retake only two of the four. But experience suggests that those who are aware that there's rust to knock off are generally able to do so. In other words, breathe, please. The major change in CSET English is that the subject matter requirements are aligned with the Common Core state standards; these call for more emphasis on informational prose and cross-curricular literacy, so you may see more questions in Subtest I that are framed in those terms (though there will still be plenty of literature). Subtest II folds literacy into language acquisition but is mostly otherwise unchanged. The Subtest III tasks are largely as they were. Newer versions of Subtest IV may substitute an analysis of a student's oral presentation for a student's creative writing - but the major tools are fairly similar. Oh, and references to technology may be updated. When are you taking Subtest II?
