Pre-test - different tests on different days or in one go?

[schooling123]

Please could anyone who had experience with this - is it better to take different tests on different days, to spread pressure?

Thank you.

No experience whatsoever.
But I would have thought different days, so if for example feeling off colour with a cold one day it doesn't impact more than one. It also maybe gives a chance to 'learn' from one before the next?

The number of tests, their duration, and age of child all impact too.
