Everyone needs to find a comfortable pace that enables them to work accurately and yet be able to finish their work in a reasonable period of time. Your pace will of course vary depending on your knowledge of the subject and the task at hand. However, you might find that you often work too quickly and have more mistakes than you should given what you know. Or, you might find that you sometimes work slowly and take a lot longer to finish or find yourself rushing at the end just to have something to submit. Your goal is to find your best balance of speed and accuracy so you can show your best work but aren't working longer than everyone else.
