I got a 4.0 for both sections. I've had almost every English teacher tell me I should be a writer in high school. Too bad I hate writing with a passion! More pills for me, thanks.
I don't know if there are any secrets to writing better for this section. By the time I got to college, I had my whole method down. I'm really good at writing essays on the fly, since in high school I wrote all of my papers the night before they were due (including my senior thesis, notecards and all.) This is probably the only time procrastination has actually been fruitful in my life.
