Hey Paco,
I just did my performance exam, and failed big-time after getting 90% in qbanks(no guarantee-I know).
I had the same experience as you, surprises by the amount of graphs and their content. Many I've never seen before and don't know what to do. I want to do the exam asap but very afraid of what I might encounter.
Can you tell us how it went(if you did your exam) and what you have done to prepare yourself?
Thank you!
