Becoming a Social worker

Hello all, my name is Marlena, a bit over 60.I was working 7 years as carer in care homes and community care. I studied level 4 in Healthcare Practice last year and now I am studing level 5, at Global Banking School in Leeds, will finish in July. I would like to become a social worker. I was presented 2 ways: 1. To study level 6 next year to have the bachelor degree and to do Master in Social work,
2. To enroll at the Hull University to study BA(hons) undergraduate social Work courses.
I don't know which way is best. Can you please advise me?
