Besides being in the process of moving I am also in the process of finding a job. Not sure if I can find a suitable postdoc position so I am currently looking if I can land a proper job, which is a job outside academia :o)
Apparently, in the Netherlands most job openings for highly analytical graduates require you to do an IQ and numerical test before you can go for an interview. Not sure how to practice for an IQ test but you can definitely practice for a numerical test. The numerical test concerns basic mental arithmetic questions. The quicker you solve them the higher your grade. I couldn't find a nice app to practice so I wrote a short python script which generates random equations using multiplication, division, subtraction, addition and after having inserted all the answers it checks them for you.
Code always looks impressive but it is actually pretty basic stuff. In python you can snake it till you make it.
I used the graphical user interface tinkter. I had never used it before. I am not a big fan of nice interfaces :P. But apparently tkinter is really easy to use. Also most of the job openings require Python skills so I get to improve my progamming + my arithmetic skills :o)
Generally Python is a fang-tastic language. Although, I still prefer doing semi-programming in Mathematica and Matlab. That Python interprets spaces and indentation is really irritating though. (No pun indented)
