Step one: Download Paradigmatic – a great resource for college students by a college student (now former college student).
I’ve only grabbed it today, but it comes highly recommended by people in the know.
Sam Freney, the whizz in question, has also produced a Greek lexicon for the iPhone available here, or via iTunes.
Two truly terrific resources. Grab them today. They’re probably worth getting a Mac for (if you’ve been trying to justify a purchase).
