Hi there
The test i would say was easy.Many of the questions were seen here,so no need to mention them.
They do not give you the results if you pass,i assume they do if you fail.
This site helped A Lot !! keep farming the tests until you feel confident.
Reading the book once though should not be that hard,i assume that version is still valid,so its what that book says that counts (check with home office to be sure).
For example , next census to take place is the one on 2011 , right? Because
the last one was on 2006 - as the book says.Although we know its gone and the real one to take place is far ahead.In general terms,easy...
Good luck !!!!
