A level: (noun)- a qualification in a specific subject typically taken by school students in the UK aged 16–18, at a level above GCSE. The equivalent in Scotland is the Higher.

It is with greater regret that I will only be very slightly active on MSE for the next year (approximately), starting from August $2021$. Thank you all for teaching me so many things, and I hope that I`ve helped some of you with my posts. Good luck and goodbye, until July $2022$.
