How do you know you are ready for the RHCSA exam?

So how would you measure your readiness for the RHCSA exam? Resource that I am using right now, I did the entire course, I got all the exercises down pat, got few index cards I will go trough but that's just instantly doable... How would one know he/she is ready to take the exam being confident he/she would pass?

I will go over the objectives and think of mini and very quick scenarios and do the objectives without any help, in addition to doing yet one more review of my prep material.
Can you clarify which course you took? The official Red Hat course or?
During my preparations to RedHat exams I have a simple rule:
If I can do all the necessary tasks from "Comprehensive review" from the official book in 80% of exam time - I'm prepared well. The remaining 20% I will have for man searching and some fixes.
When there is no "comprehensive review" in the book (i.e. EX236) I'm preparing the list of tasks that I can probably get on exam and follow the previous rule.
This is similar to what I do. I aim to create some sample scenerios based around the objectives and see how long it takes me. I aim for about 50% of the total time.
Where a command is too complicated/tedious/dull to remember verbatim I remember a pointer e.g. look at the man page, or use the gui for this bit, or --help that kind of thing.
