Updates for OCR Leel 2 Unit 4
What a nightmare!  Trying to unravel another's data sets while retaining accuracy and cohesion is high impossible when you don't have to original data sets to go on, but this is a start.  However the learning Sage2-2 provides is sound even if some bugs in the data still remain.  Anyway download all the resources afresh and work quickly through them.  Hope the changes are useful, and now to the other projects!
