Like some schooldays of the past (3)

Ross

I believe the answer is:

old

I'm a little stuck... Click here to teach me more about this clue!

'the past' is the definition.
(old is a kind of past)

'like some schooldays' is the wordplay.
'OLD' is hidden within the letters.
However, I'm unsure how this is indicated.

'of' acts as a link.

Can you help me to learn more?

(Other definitions for old that I've seen before include "Wild clematis" , "Elderly" , "Much-used" , "Former, previous" , "out of the ark" .)

I've seen this clue in the Evening Standard.
