Yes, at last I have worked my way through the Publishing Training Centre's Basic Proofreading course, and I've ended up with a pass with merit. I'm jolly pleased with that, as a whole lot was going on when I took most of the exercises and my concentration was scarcely 100%
What's next?
Well, in NOvember I plan to attend the Proofreading Problems one-day course in London, run by the Society of Editors and Proofreaders (SfEP), and then get on to their "mentoring" system, which will give me the taste of some real proofreading work. On the assumption that all this comes to pass, then next year I plan to take the copy-editing course as well.
On which note - I cannot resist writing this - I got myself a copy of the copy editor's "bible" (Butcher's Copy-editing) and... found an error in it! I passed this on to my proofreading tutor, who apparently will pass it on through the "appropriate channels", whatever they are. I am not sure if SfEP will then excommunicate or exalt me!
