New love of triangles
"My daughter was at secondary school and I was having this recurring nightmare," she says. "I'd always sat and read with her, but I knew that one day she'd say, 'Mum, can you help me with my maths.' I knew it would come and I was terrified."
She enrolled on a maths GCSE course at the Adult College of Barking and Dagenham, where she had passed English GCSE. She admits she found the maths hard - it took her three years to get GCSE.
Ms Browne, a 38-year-old mother of two, is studying psychology at the University of East London. She says her maths qualification helps her at home and with her degree.
"There's a lot of maths on my course - you have to get into statistics, tables and graphs. I understand them now, but I wouldn't have done before.
"The other day, my son asked me about isosceles triangles and other types, and I knew what he was talking about."
