Of course it isn't. There are 60 questions all testing very much the same aspects of 'intelligence' and there is no timing involved at all. In a proper IQ test, pattern recognition and series development would be tested but there would be many other aspect tested too. Moreover, IQ tests are timed.
I'm sorry, I can't bring myself to take an IQ test which has obviously been created by people who aren't intelligent enough to do a simple spell check before they publish it. The grammar is also appalling.
Go to this website for a really fun way of finding out what your own IQ is for nothing. http://www.iqtest-center.com/index.php Did it myself and it didn't take long and was very enjoyable. Scored higher than I thought I would.
