I got a zero.
But seriously, you must be careful to interpret the questions the right way. For example, "I share absolutely nothing with others"
must be taken to mean "ABSOLUTELY nothing with ANYONE else I might ever know in the world", or "I hear or see things others can't see"
must not be taken as "I pay attention to a lot of small details that other people generally don't care about".
That test is supposed to check whether you have psychosis or not. If you are schizophrenic you have psychosis, which means you can lose contact with reality... So you "hear or see things other can't see or hear", for example you are
convinced that aliens are talking to you and want to convince you to take over the world for them... for example. But you must be
convinced of that, you must take such things as
real. So, for example, intrusive crazy thoughts are not "psychosis", because you recognize they aren't real.
That's schizophrenia and psychosis, as far as I know (but I might be wrong).
