Hey there, Robin!
Yes, the points you receive from the classes contribute to your house's points. The first statement you wrote from Your Personal Page means that your professor (or someone) already submitted the 30 points you earned. The second sentence means that the 30 points submitted were not yet approved by the head office, so it is still not reflected there (and in your points tab). Don't worry, once the points are approved by the head office, it will be reflected there. Hope I answered your question.
