Part 1 exam: how email actually works
Twelve questions across everything Part 1 taught. No feedback until the end: a score, a verdict, and the exact lessons to reread.

The checkpoint's drill and scenario were practice: feedback after every answer, nothing at stake. The exam is the committed run, twelve fresh questions with no feedback until the last one is answered. The score comes with a verdict, and the verdict means what it says: it tells you whether to start Part 2 now or spend an evening rereading first. A miss here costs a reread. The same gap resurfacing in Part 2 costs more.
Part 1 exam: how email actually works
12 questions covering every lesson in this part. No feedback until the end, so answer the way you would in front of a client: committed. You get a score, a verdict, and the list of lessons to reread for anything you missed.
When the verdict reads ready, Part 2 is waiting: SPF, the first record that proves who may send as you.
