AP Language and Composition strategy?

Okay, so this may be (it definitely is) a stupid question. Anyways, I’m taking the AP LaC exam next week and I got to thinking…what would happen if I did really well on the multiple choice (maybe 80-85%) and then spent the allotted time for the free response only writing two REALLY GOOD essays (8’s or 9’s) and then whatever remaining time busting out a third, very mediocre essay?

Again this is just a hypothetical…

You would get a 5.

But really, this is sooooooo hypothetical on so many levels. Just spend the time preparing. Good luck.
