MY LAST YEAR AT SCHOOL

MY LAST YEAR AT SCHOOL 
As the new academic year dawns, high school is the sun around which Eric Ewing's life orbits. But there are plenty of other spheres of influence for this teen: work, sports, and his passion — computers.
«I love computers. If all the time I spend on my computer counted as homework, I'm sure I could have the highest grades», he says.
Born and raised in Chesterfield, a city in eastern Missouri that stands on the Missouri River, Eric has just started 11th grade — his second year at St Louis High School. He is a solid 3.0 student (the highest GPA is usually 4.0), but he admits to having developed poor study habits. «In elementary school, if you didn't do your homework, it didn't hurt you. Then all of a sudden middle school comes up, and high school, and it's getting harder and you're not doing a real good job on homework. This year, I'm trying to change all that.»
This semester, he's taking world history, English, geometry, biology, Latin (which he says will help with the English portion of the SAT, a standardized college-aptitude test), photography (his only elective), and health.
The final bell at school merely signals the start of the rest of Eric's day. Several times a week he spends at the local Dairy Queen restaurant, where he works at the counter till 10:30 p.m. He'll get in a little bit of homework there — especially in winter, when demand for ice cream drops off — and then finish it at home. His parents, who own an embroidery business and work from home, don't mind his involving into fast-food business — as long as it doesn't distract from his homework. He's saving for a car, hoping to get his driver's licence next June. When he's not working, Eric goes home for a marathon computer session. He surfs the Internet, plays games, messages friends, listens to music. TV rarely enters the picture. As for future plans: «I'm trying to decide what I want to do after school, but it's more of a thing I'm going to look at a bit later».
