No it's not.
It's accepting that Frankie over there needs little more processing time.
Or that Sophie over there, broke her arm 2 days before her exam, so was allowed a scribe and extra time is required for the scribing to occur.
Or that Connor has dyspraxia so needs a bit more time to physically write the excellent answers that demonstrates his 9 level knowledge
Or that Emma has been diagnosed with extreme anxiety because of the pressure her family put on her to do well at school and she needs a bit of extra time to compose herself.
Oh and Tetyana is an evacuee and English is her second language and needs just a little extra time to translate the questions and answers.
Or any other valid reason.
Don't be so narrow minded.
