Am I doomed?

My centre is nearby but i saw the latest reviews in maps (1-2weeks prior) where they said its like a factory shed with no proper ventilation nor ACs. The temperatures is hitting ~40°C that afternoon.

AM I ACTUALLY COOKED OR IS THERE ANY WAY TO SURIVIVE THIS HEAT DURING EXAM. All advice appreciated. Dont tell me shit like just keep doing the sums bro and stuff because heat can reduce your cognitive ability and make you dumb fr. Optimal temperatures were 24-25°C which ik isn't possible rn. But how do we survive thie heat before we get cooked literally and figuratively.

Unrelated flair dont mind
