Ah-ha, finally I found the case-study. Okay, I honestly wasn't looking that hard for a while. Nope, after I'd moved some laundry, had written a bit, read some, I decided really, it wouldn't hurt me to check. Plus it might shut up that voice that calls itself my conscience.
First place to check, that massive pile of papers that iI never bothered to give folders. Before finding the case-study, I found 5 copies of the exam case study, 3 grading assessment sheets for TOK and 3 assessment sheets for business. Opps.
