Just that really. Finally got my ML3 through 2.5 months after submitting my forms.
Despite me trying to work it out I've got the numbers wrong. Now I'm trying to understand Tax, NI and Student Loan deductions and it feels absolutely impossible! I get very little back from HR and can't find any kind of online calculator to help.
I can't believe it's this hard, do most mothers just have a rough idea and hope for the best?
