GRANVILLE, Ohio (AP) - Granville High School senior Chris Asplund said he's not much different from any other high school seniors.

After all, there's 23 just like him who got perfect scores on the ACT Assessment exam.

''I'm usually prone to stupid mistakes,'' said Asplund, one of two Ohio students to get a perfect 36.

Asplund took the test, one of two primary exams colleges use in considering prospective students, along with 345,000 other high school students this year.

The test is composed of mathematics, English, reading and science-reasoning questions.

Asplund and Abigail Martin, of Centerville High School near Dayton, were the only Ohio students to record perfect scores, according to Kelley Hayden of ACT Inc., located in Iowa City, Iowa.

The average score was 21 nationally and 21.4 for Ohio.

''A lot of the questions are cognitive. I don't know how much studying would help you,'' he told The Columbus Dispatch for a story Saturday. ''A lot of it is being able to puzzle things out.''

The 17-year-old Asplund is leading a busy senior year at the school that is about 25 miles east of Columbus. He's a National Merit Scholar semifinalist, student council president, runs track, referees youth soccer and participates in five school musical groups.

''He's an extremely gifted student already,'' Granville counselor Mike Robertson said. ''He has this natural talent. He's a gifted pianist. He's taking pretty much a full load here plus courses at OSU and has boundless energy for information and he's a good-hearted person.''

His classmates help him keep his feet on the ground.

''In English class recently I got shot down when I was making a point,'' Asplund said.

''Someone shouted '36' and discussion just came to a halt,'' he said.

Chris wants to attend Princeton University and has been spending his recent Saturday nights writing scholarship applications.

''More than I can count,'' he said. ''But I figure four hours of work for $10,000 is probably worth it.''

Asplund keeps his ACT achievement in perspective.

''On college applications, they want the SAT score more. They don't care so much about the ACT, but some colleges will accept them if you haven't taken the SAT.''

Asplund didn't fare quite so well on the SAT. His score of 1,560 fell short of a perfect 1,600.

But it was good enough to place him in the 99th percentile of students taking the test nationwide.

''That's pretty good. I'll stick with that,'' he said.
