For Contributions Based Jobseeker�s Allowance [JSA(CB),] the current rate is �60.80 per week. For Income Based Jobseeker�s Allowance [(JSA(IB),] the rate for a couple is �94.95 (assuming one of yous is over 18)
If you have an income (such as yir wee pension,) the first �10 pw is ignored but anything above that is taken off the allowance.
It sounds like they may have awarded the JSA(IB) when they had the pension income details verified and that gave �73.
If you get any income for being a student, that may have wiped out the income-based part and all that is left is the �60.80 JSA(CB)
Best thing to do is �phone them up and ask them to explain it to you.
