Judging by their spelling, design and waffling in the description of their photography "course's" modules, I'd avoid them.
I'd especially do so if their students or, worse, their teachers are responsible for the photos in their galleries.
Judging by your existing photos you seem to know what you're doing in terms of using your equipment and can use your equipment to take photos that are pleasing overall, so if anything I'd think you could look into working as an assistant with established photographers who's work suits what you want to be able to do. While doing so you'll obviously be directly responsible for influencing the light they're working with and can get an idea of
how they work with their surroundings and clients to get the shots they want. Reviewing the photos they get from a given day against what you experienced that day should gradually give you a more firm grasp of how to do those things yourself. At that point you can begin working as a second shooter to the weddings as opposed to being an assistant, and see how well you're able to emulate the results you want to achieve.
I believe many wedding photographers with assistants don't mind their assistant having a camera on something like a blackrapid strap so that it's out of the way, but accessible should the assistant not be needed for anything at any given time, so that the assistant can instead take some photos of the guests and the like as well.
Otherwise, if you're certain you want to do a course, look into Vega's courses.

I'm fairly certain it's their brochure I picked up at Orms in December that was filled with 2011 graduates' photos, and judging by their output, I'd say it's a course worth attending.
