ROUND ROCK, Texas — A typical image taken of the surface of Mars by a camera is 11.2 gigabits in size. A tracking station on Earth can receive data from the spacecraft at a data rate of 3 megabits per second for a maximum of 11 hours each day. If 1 gigabit equals 1,024 megabits, what is the maximum number of typical images that the tracking station could receive from the camera each day?

Don’t know the answer? That’s OK.

There’s a student in Round Rock ISD who most assuredly does.

The district announced that McNeil High School junior Vinh Ton this year earned a perfect SAT score of 1600.

“After I had left the SAT I wasn’t so confident I was going to get a perfect score,” Vinh said. “The test was much more difficult than the practice tests made me think it would be.”

According to the district, Vinh started preparing for the college entrance test over winter break, completing numerous practice tests and paying close attention to the amount of time he spent on each question.

Vinh said grammar and reading were the subjects he felt least prepared for but credited his teachers at McNeil for getting him over the hump.

“My teachers prepared me well for the exams,” Vinh said. “I think they are all amazing and have a lot of dedication to their students. Their dedication helped me understand what to expect from the tests, get me motivated to study and appreciate what they are trying to teach me.”

So what’s next for Vinh? He’s hoping his perfect scores qualifies him for a National Merit Scholarship next year. He’s open to attending college locally but will explore Stanford University and Harvard University as well. He’s considering a career in health science.

“Vinh makes me a better teacher. He’s anxious to continue expanding his knowledge base,” said English teacher Deborah Palmer. “It’s all Vinh; he’s amazing, brilliant and works hard.”
