I havn't asked him when I will go solo, and I won't!! I don't think it would help to know in advance!! I was only interested to know what others have achieved, and I've got a rough picture now - many thanks for the answers.
I did ask if I was wasting my money, and he responded "definitely not"....but then he would say that anyway. Generally I'm happy with my progress, though I'm finding the discipline to study for exams difficult. However, I'm plugging away and getting there.
I'll keep you informed.....cheers all
