I recently did a typing test at an employment agency and I was told to 'pace myself'. What does that mean

This means to give equal attention to the performance as well as the time. Just as you are supposed to "pace yourself" for a marathon, you shouldn't go all out and run too fast at the start of the race only to lose all your energy at the homestretch. During the typing test, this means you mustn't type too fast at the beginning and commit a lot of errors or lose gas towards the end of the test. Speed plus accuracy is what they're looking for :-), not just one or the other.

Hand eye coordination. You want to be typing what you are seeing or hearing. The tester probably felt you would reduce the number of mistakes by slowing down a bit. She was just telling you to relax.

It means pace yourself to avoid errors. i wouldn't take to be a bad thing.

Pace is a brief stop. You are asked to type with paragraphs, sudheads,or punctuations.

Typing tests usually have time limits. To pace yourself has something to do with the time element, so you can type everything within the time limit. It means type at a consistent pace. For instance, if you're typing too "slowly but surely" at the start and ending up otherwise, you'll have to pace yourself :)

Pace, usually has do do with speed, so you might have been typing too fast or too slow.

It means... type faster! type faster!
