Classes are identified by URIs, not by strings.

Hello Andy, shouldn't there be the class name to which we assign new

Dave run this code and it works for him, but I do not know why, it does not
work for me.

The rules have some syntax problems:
"( ?x http://www.semanticweb.org#GPA ?score + )"
as mentioned earlier in the thread then
"greaterThan(?score, userscore) "
but userscore is a java variable.
Also
inf.listResourcesWithProperty(RDF.type,
"GoodStudent")
uses a string not a URI so if not going to find anything.

Are you sure that this code compiles?
Property prop= model.getProperty(ns,"GPA");
ns is a String in your code, the method expects a Resource object is
first argument. You totally use the wrong method here, as it returns a
Statement.
Model::createProperty(String nameSpace, String localName)
would be the method to call, or even better as you use an OntModel
OntModel::getDatatypeProperty( String uri )
