questions about RHCSA

Hello everyone!
Now when I'm on my way to RHCSA (and maybe RHCE), I thought it would be a very good idea to ask some questions to others who know much more than I.
I'm preparing for EX200 v7, using CentOS 7 (I found it more friendly than scientific linux
, by the way they are actually same) and official Red Hat documentation, also using M. Jang's book. Have set up several virtual and physical labs. But there are some points that make me nervous. for example I can't understand what does Red Hat mean when they say:
Does this mean that I should use man and info pages or on the contrary - this won't be good idea?
And just one thing: when using kickstart, I mentioned that installing OS takes 20< minutes and sometimes much more. At first I thought there was a problem with my lab set up, but when I searched in google, I found several people also complaining about this problem. I'm afraid that this might be a problem on an exam when time is everything.
Any answer and advice will be welcomed

Note: Red Hat may use applications during the exam that are not included in Red Hat Enterprise Linux for the purpose of evaluating candidate's abilities to meet this objective.
- Locate, read, and use system documentation including man, info, and files in /usr/share/doc

2. Don't worry about about the bit in red - Red Hat are not out to get you, or catch you out. It's just saying that they might use additional software that you do not know about. Nothing to be concerned about.
3. 20 mins for a kickstart install is probably about normal. It is piecemeal, it installs every package one-by-one, it is not an imaging software like Solaris Jumpstart can be.
You don't know that. He might.
It's on the objectives and he should learn it.
The key thing to remember is, lets say there are 20 items on the objectives. An exercise to prove each could take a couple of minutes to 10/20/30 minutes. There is a set time in the exam, if you ask you do tasks that are 10-20 minutes then there is less coverage they could get than if they stuck to the "quicker" tasks. Likewise if they did all the quicker tasks then they might not be able to test the tricky long-winded tasks.
The result is almost always a combination. Given how long it tasks to build a server from scratch it might be a fair bet to say it's unlikely they will ask you to do it - but they could, and you must be prepared to it either way.
In any case, it's all good practice.
You also signed a Non-Disclosure Agreement to state that you will disclose information about your exam. They could revoke your certs.

I'm using old version on RHEL6. Yes, I know that many things have changed, but anyway many things does not
