South Korea's annual college entrance exam has begun to be distributed three days ahead of the test date. 

The Education Ministry said the College Scholastic Ability Test(CSAT) question and answer sheets will be transported to all 86 test zones across the nation from Monday. 

About 400 people will be responsible for transporting the test papers, with police guarding the transport vehicles.

The question and answer sheets will then be kept under tight security and moved to about 13-hundred test sites on the day of the CSAT on Thursday. 

A total of 493-thousand-433 people will take the test this year.
