About LockDown Browser for CLT

During an online exam, LockDown Browser will prevent you from going to other URLs, switching applications, copying questions or printing. It essentially locks you into the exam until it's submitted for grading. This is NOT a limited-feature version and there are NO advertisements of any type.
