I wonder if you can take notes in a pice of paper while taking your numerical reasoning test. It will really help.
Also, can you have a physical calculator or only the one given on your screen?
I've participated in a few EPSO competitions, all at the same Test Centre in Athens. In each and every time I was given a calculator and, obviously, also could use the on-screen one. About your first question, you are being given a small booklet with 4 A4 pieces of paper and a pen (all of which you have to return at the end of your tests) where you can take notes or perform math operations let's say (I think, until last time, they were providing you with a marker, an eraser and a small whiteboard). In my opinion, it is quite time consuming to do so, try to avoid it, you only have a couple of minutes for each numerical question.
Do we take all reasoning tests together? Or are there breaks between tests?
You first take the verbal reasoning test, you 've got 5 minutes I think before the numerical test, then a 20 minutes break which you can cut short anytime and, finally, the abstract reasoning.test.
Thanks a lot Niko!
