help me, obi-wan flist

Does anyone know of any Attic Greek drill sites like Praxis for Latin? I'm using Shelmerdine's Introduction to Greek; I kind of doubt that there's a cult of Shelmerdine the way there is a Cult of Wheelock, but there aren't practice exercises in Shelmerdine and I, um, less that convinced by my prof. I'll probably end up asking her, but I wanted to see if anyone had any suggestions first. I'm old-school; I need to do a lot of drill to get anything down early on, which is why my first Latin teacher was ideally suited to my language learning temperament.
