This site is run by two Swedish Mensa members who are fond of puzzles, IQ tests, and intelligence in general. The logo of IQ300 incorporates the three most common flavours of IQ tests: spatial, numerical, and verbal.
One of the two administrators is Henrik Eriksson (firstname.lastname@example.org), who has a PhD in Computer Engineering and a MSc in Applied Physics and Electrical Engineering. He has been a member of Swedish Mensa since 1994 (i.e. for more than half of his life). For now the other administrator (email@example.com) wishes to be anonymous.
Henrik has achieved the following scores:
Top 0.2% of 60500.
Strange and difficult, my first HRT.

First pure verbal test. Got better score than expected.
High-range on-line timed matrix reasoning test.
A lot of crystallized intelligence needed.
