Research and redistribution boundaries
This is not the student's original UCL ZIP package: those sources have uncertain redistribution rights and may include real research records. This public edition reproduces the learning objectives with entirely invented data and independently authored practice. It is not an official UCL assignment or examination answer key. AQ-like scoring is an educational exercise, not diagnosis.
