I recently received the disc in the post that outlines the course at BGS. I have to say that I was very impressed - the presentation is very professionally put together. I live in Vancouver and after my initial email it arrived in the post within about 5 days. This is in contrast to OATS who in reply to my enquiry emailed me a rather basic .pdf attachment outlining the course content. No postal reply at all or any blurb sent to me which I found rather unimpressive.
Looks like I may well embark down the BGS route. I will have my weekdays free, so am hoping to crack it in about 8-9 months.
