Found in Stanhope Street, NW1. Text reads: “IELTS 8: Examination Papers Cambridge ESOL, CD 2 of 2”. Of course, CD 1 of 2 was nowhere to be seen. Had this educational aid been thrown away after an exam in a moment of joy (no longer needed)? Or had it been trashed in advance of the exam in a state of despair (why even bother with revision)?
