The domains of expertise on IPVM are numerous and overlapping, and taken together are quite broad. They range from practical to financial to topical to theoretical, nobody knows everything about all of them, everybody is a 'newbie' at some of them.
Though sometimes, once you have acquired some facility in one discipline, its easier just to think that the other subjects are ones that you're just not interested in, rather than to say one is a 'newbie'. Or even worse one can start to believe their superiority in one area assures the same in others.
But those, like you, who willing brandish their 'newbie' badge openly, are usually more experienced than they let on, and only use such a label more than others because they allow themselves to be aware of that which they don't know. And just that attitude is likely to hasten their progress more than anything else.
tl;dr
On a more practical note, I would recommend using the existing quizzes (more please!) to gauge the composition of the site, as it is more specific to subject area. You can tell by the averaged scores roughly where you fit in.
Good Luck, fellow 'newbie'!
