It was fairly pleasant and fast-paced, but not as easy as some of the other reviews on this site might make you believe. To be fair, my perception might have been thwarted by my anxiety issues and overthinking everything – which is probably what you should avoid exactly if you want to score well on these tests. They are fairly straightforward, but there are some tricky things here and there: *Venn Diagram/Set Notation: It's a mixed back of very basic stuff (just shading in overlaps and unions), and some things that require more thought (3 things to shade, 'extractions' and problems using numbers). I think what you need to be careful about here is not to stress out over the more obvious part and leave yourself enough time for the harder questions at the end. I would really advise digging more deeply into Venn diagrams than the videos they offer you. *IT aptitude test: You can't really prepare for this, but it is a good idea to brush up on the knowledge you do have (be it business or IT). Be calm and don't spend too much time on certain questions – a lot of the questions are behavioural, some are spelling and grammar related (be really careful here; it's easy to make mistakes) and there is some 'logic'. For this, I would just practice some online logic tests, if possible. *Math tests: This was rather basic GSCE Maths, but you really need to be comfortable without using a calculator. Again, try not to spend too much on specific questions? In the end, it's really more about being able to concentrate / not losing your cool than any specific kind of skillset. The interviews are really important -- you should show your enthusiasm and motivation here :)
