As far as I know, no one really uses Apprentice anymore (not that I'm putting Apprentice down; in fact I loved the simplicity of that application, it's just that MWS does so much more).
I guess your best bet would be to find games on MWS and just take them with a grain of salt if your opponents are inexperienced/not very good. Whenever I find someone who knows what they are doing I ask them for their IM information and add them to my friends list. You should probably do the same.
