All right.
One issue on the exam might be stress.
How can you reduce stress on the exam?
Well, first advice, try to handle tasks in order.
Some tasks may depend on solutions for earlier tasks.
If you don't know how to proceed on a task,
flag to revisit and work on another task first.
So make sure you first clear all the questions
where you do know the answer and then
start spending as much time on the questions
where you don't know the answer.
It's unlikely that you are going to get
the points for these anyway.
Important, in case you are getting stressed or even worse,
if you're getting blocked, you can have breaks in the exam.
You can have a break after the first hour and every next hour.
But RHCSA is only two hours, so you could have one break only.
Now, my advice is when you get blocked
and you don't know what to do anymore, request a break.
Often, the fact of walking away from the exam environment
allows you to think about the question
in a different context, and you might suddenly see it.
So do ask a break in case you need it, in case you're blocked.
