I 'attended' an online course called 'Pitch Your Novel', run by the Australian Writers Centre. It was an on-demand course, with no face-to-face teaching. Once you purchase the course, you are able to access the course material for 12 months, and much of it is available to download and keep. Novelist Natasha Lester is the tutor and she presents each of the modules clearly and concisely in a pre-recorded video with an accompanying handout. Natasha's organised, type-A personality struck a chord with me, and I watched some parts of the course more than once, in particular when I was truly ready to start sending queries to agents.
It was one of the most valuable courses I have done. I have found all four writing courses I have done with the AWC absolutely amazing and worthwhile, and wish I had invested in them earlier.
To have the best preparation in preparing manuscripts, pitches and knowledge about the publishing industry, invest money in as many courses as you can with the Australian Writers' Centre. Research the courses and pinpoint the best classes that will help you on your journey to becoming a published author.
