Yes, but what qualification? City & Guild? NVQ? Something else?
Without knowing what the syllabus covers, it's hard to advise. When I was doing city and guilds at level 2 and 3, I went and spoke to the college first to understand what the course was like.
Sometimes they won't let you onto a higher level course without you having completed the lower level one first, either there or elsewhere. That way, they know everyone is up to more or less the same standard. Or they may ask you for a portfolio of work so that they can try and gauge what level you are.
