Should I use a training provider for Level 2 aat

Hi,

I've recently taken a different direction in my career from working in a bank and am looking to go into accounting. I have some accounting knowledge but for argument sake lets say I have none. I'm looking for some guidance on whether it would be possible for me to learn level 2 without a training provider. My plan would be to buy the books for level 2, study them, not sit any level 2 exams and move on to level 3 with a training provider.

Level 2 will cost me roughly an extra £1000 with a training provider + all exams. From what I hear level 2 isn't required to complete the aat qualification only levels 3 and 4 are.

So my questions would be

1. Could I learn all I need to know from the level 2 books in order to start level 3?
2. What publisher would be best, or will any suffice?
3. Would having level 2 on my CV significantly help me getting an entry level job in accounting?

Thanks.
