It’s so important, but so many students don’t do it. The most common reason for this is because students leave it until the end of their exam/test, so there’s simply not enough time.
My suggestion is to keep checking your work as you write. Every time you finish a sentence, read it again. This will stop you from making silly spelling/grammar/vocabulary mistakes because you’ll be checking your work as you go, thereby saving you marks in the process.
I hope that was helpful!
