Another useful item from David Meadows: Classical Greek online here.

The group starting on Monday 18th June will be using Hillard and Botting: Elementary Greek Exercises. This is a very old-fashioned book, but, boy, if you get through it you'll know your elementary (well, and not so elementary too) Greek grammar backwards, forwards and sideways.

Something to commend to a dead-keen Latin pupil who wants to learn Greek, perhaps - or even to do yourself, if you missed out on Greek.
