The Indian Prairie Public Library at 401 Plainfield Road in Darien invites teens in grades 10-12 to participate in a free, proctored practice Preliminary Scholastic Aptitude Test (PSAT) from 10 a.m. to 12:30 p.m. Friday, Aug. 3.

The practice test is designed to help students identify their test-taking strengths and weaknesses before “the real thing” during the school year. Each student who takes the mock test will be contacted about his or her analyzed test results.

Students should bring sharpened #2 pencils and an approved calculator for the test on Friday.

The library asks that those who have registered but are unable to attend give a 24-hour cancellation notice so other students will be able to participate.
