You'd still have to attend to do the BA test and interview at FTE's assessment centre, you just wouldn't need to do the FTO tests too. One guy was in that boat on my first assessment day and was waiting around for a while between things.
I think FTE's view is that your test scores from six months ago are similar to how you'd score now, and either good enough or not. As it's the benchmark that's changing and not your scores; there's no real need to take them again.
