What to do?

I'm  so confused about what I want to do next year. I had my course all planned. I'd do the Youth Work Diploma and then do Social Welfare via distance ed at CSU. Now I am really considering scrapping all that and doing criminology either at UNSW or more likely UWS.

The confusing part is whether I should continue doing the diploma. I doubt it would get me any advanced standing at uni (for example if I was to do something like Community Welfare at UWS I'd get recognition of prior learning for a whole year's worth of credit so it would only take me two years instead of three) but it would give me more of a broad range of career prospects. If I do Criminology I am setting myself firmly down the juvenile justice path.

What's stopping me from 100% staying with the diploma is that so many jobs require a degree. So if I know now which degree I want to do, why am I wasting my time with another year of something that isn't going to get me to my ultimate target?

The last thing I need to think about is how late I've left it. I need to decide this pretty quickly if I want to start a degree next year. And if I do then I need to register for the STAT test pretty quickly but then apply late and have to pay a fortune to do so.

I don't know. I'm so confused.
