I would not recommend ULaw. It's a qualifications mill. This may not matter too much if all you need is to grind through the requisite qualification.
Studying part time would allow you to earn some money which could assist when you take the Bar course or the SQE, and to reflect on whether you do wish to pursue a career in the law.
You could also read more widely in legal topics outwith the course. Doing that would probably make you a better lawyer. When I did the PGDL many years ago, the workload was so light compared to my degree that I had time to read a lot of legal history, public law stuff, and jurisprudence. That made me a better lawyer.
If I was doing the training again I would bone up on company law and equitable remedies, but I did not know at that time that I'd end up a commercial Chancery lawyer.
A year or so at this stage of your life is neither here nor there. My general advice to all students in their twenties is don't rush.
Good luck!
