It is different for each part. That is why every part has its own guide on this site: what
exactly you are given, where the time goes, and where most people stumble.
Start with DUO itself. There are free practice exams: 4 for Lezen, 3 for Luisteren, 3
for Spreken and 3 for Schrijven, and they are exactly the real format. Do all of them. Two
practical tips from DUO: take them on a computer, not on your phone, and DUO’s
Spreken practice exam does not work in Safari.
In DUO’s official practice exams: Lezen 25 questions (4 exams), Luisteren 25 questions (3 exams), Spreken 16 questions (3 exams), Schrijven 4 tasks (3 exams). DUO advises taking the practice exams on a computer; the Spreken practice exam does not work in Safari.

Three or four practice exams is not much if you want to learn a format. That is why this site has

teacher.

With my students, the biggest difference between passing and failing is rarely the level. It is the time. They do know the words, but they have never practised with a clock. Take a complete practice exam with a timer at least three times before you take the real one.
