In the Indian subcontinent , Russia, Middle East, Africa, and China, engineering is one of the most sought-after undergraduate courses, for which entrance examinations are highly competitive. In Egypt, the educational system makes engineering the second-most respected profession in the country (after medicine); engineering colleges at Egyptian universities require extremely high marks on

4824-506: The title of engineer is regulated by law. In France, the term ingénieur (engineer) is not a protected title and can be used by anyone who practices this profession. However, the title ingénieur diplomé (graduate engineer) is an official academic title that is protected by the government and is associated with the Diplôme d'Ingénieur , which is a renowned academic degree in France. Anyone misusing this title in France can be fined
