High school seniors are taking the state-sponsored College Scholastic Ability Test for the 2005 academic year.

Some 610-thousand students are taking the tests, which began at nine a.m. Wednesday at some nine hundred locations across the nation.

With the test scheduled to end at around six in the afternoon, the entry and parking of cars within two hundred meters of test sites are being restricted.

Government workers and employees at large companies were advised to report to work by ten in the morning, an hour later than usual, in order to avoid traffic congestion related to the exam.
