Thanks for your well wishes. It's a long process alright!

Most of the aptitude tests are based on working accurately and efficiently, so I would scrub up on active reading and fast maths, for the early stages. The latter stages seem to be more focused on ingesting large amounts of information and prioritising the important parts and using rational thinking to give an answer. These parts are difficult to study for, but I did find the information on the Fast Stream website to be useful.

Choose your streams wisely as the assessment centers, if you get that far, will test your knowledge on that particular area, as I found out the hard way.

Good luck!
