Which test should my son or daughter take? Test prep expert Lynn Carnegie will help parents and students answer this question. She will be giving a free seminar from 10 to 11:30 a.m., Thursday, April 20 at the New Canaan Library to help freshmen, sophomores, and juniors — and their parents — create a testing plan that will work for them.

“Every student’s circumstances are different, so there is no single answer to the SAT or ACT question,” says Carnegie, founder of local test prep company Carnegie Pollak. “Creating an individualized plan maximizes the student’s time and reduces stress.”

In addition to discussing the SAT and ACT, Carnegie will also help students create a plan of attack for finals, AP Exams, and Subject Tests.
