Not sure what the entrance requirements are as I have a previous qualification and they never asked me about anything else. Probably best to give them a call.
Small groups if going the full time route - better than being lost in a sea of people. Same goes for the distance learning. I have had no problems at all with them, though I can't compare them with anyone else as I've not experienced anywhere else. But so far have got the passes I need so they must be doing something right!
