I wouldn't ever assume that a lower entry requirement means that the recruitment process is easier. I was going to apply to the GLS but decided against London.
From what I've seen, the first stages of the GLS application process doesn't take into account your university, degree classification, work experience etc, it mainly focuses on the different tests you'll be asked to complete. But inevitably they are going to look at those things eventually, and I think you'll find it extremely difficult to secure a TC with no legal work experience.
I have no idea what the rest of the recruitment process is like and what kinds of questions they'd as you at interview, but you'll find it difficult to answer competency questions without any legal experience. Do you have any non-legal work experience that could help with this? Anything like a part time job or some charity work?
