You are given 360 Minutes if your test is in English, I took mine recently and it was the toughest and longest exam I have ever taken. You will get a break somewhere in between; Use it.
The only place you will see "real" questions is on the exam itself.
There are plenty of places with practice questions (including our very own), but none of them have been taken from the exam itself.
If you do find someone who claims to have real exam questions, they are either lying or will put you at risk of having your certification permanently revoked for an ethical violation (cheating).
