I’d suggest doing one of the consolidated ‘upgrade’ courses such as
Course 20417A: Upgrading Your Skills to MCSA Windows Server 2012
rather than a shed-load of courses starting with the very basics which you clearly don’t need.
Regardless of the trainers ability, these at least give you the opportunity to get some hands-on trying out lots of different technologies before hitting the exam. And (for me) it means I’m not having to do that whilst at work or in my own time.
edit: sorry, just re-read the question. No experience of Manchester-based courses. We used to run some in Leeds but now only do them in Southampton or Poole. Combine it with a few New Forest / Purbecks rides :-)
