NIC contributions going forward

OldBeanz

Having just drawn my works pension at 61 I will get the £115 pension when I am 66 in Jan 2020 due to being contracted out for almost all of my career.
I have no intention of doing any serious work in the meantime but do put in a few hours each year at the school as an invigilator where I am taxed as an employee and will probably earn circa £1k over the year.
What should I be doing about NIC contributions to max out my eventual state pension?

Class 3 still £14.10 a week.

Class 2, self employment, is cheaper while it still survives: £2.80 a week. It would mean having some self-employed income, however modest.
