Answer Key

PSSR exit exam questions and answers — Set 15 — Personal Safety & Social Responsibilities

Set 15 of the Personal Safety & Social Responsibilities (PSSR) exit exam bank — 30 of 786 questions, with the correct option marked and a one-line explanation for every one. Read it end to end, jump to a single set, or search it — then sit the same bank as a timed paper. The real DG Shipping exit exam is 30 marks with 15 to pass.

These are the bank's original groupings. Practising deals the whole bank out again every time you reshuffle, so a practice “Set 3” is a different 30 questions each time — the set numbers below are the source file's, and are only used here so the key stays navigable. Options are listed in their original order with fixed letters; when you practise, those move too.
