The Class B theory exam is short and strict. Here are the exact numbers.
What counts as a mistake
Every unanswered question counts as wrong, so answer all 30 — flag the tricky ones and come back. Three wrong answers and you're out, so the margin is thin: build the habit of finishing your mock exams with one mistake or fewer before you book.
If you don't pass
Your DGT fee covers two attempts; here's how resits work. The fix is almost always the same: drill your weak topics — road signs, priority, speed limits — and review every mistake until it stops catching you.
