The best thing to do is to try to solve the questions as much as you know with a cool head.

Being cool–headed is necessary for proper and sound thinking. There‘s nothing to be gained by panicking or feeling desperate.

In case of a practical examination, you can try to do as much as you can and then leave the rest.

This will result in your getting more marks since not everything has to be done perfectly.
