Scoring for the APs?

<p>How does the scoring really work? How important is a scale? I'm taking the AP Bio on Monday, so I'm taking some practices and wondering what I would need for a 3/4/5? Sorry if the topic has already been brought up, but I couldn't find a thread about it and with all the studying I have to do, I don't have a ton of time to look through the past few days. Anything on scoring or the Bio test in general would be great. Thanks and good luck to anyone else taking Bio!</p>
