(*) In France, the CPGE program consists of two to three years of extremely intensive preparatory classes to the national competitive entrance (written and oral) exams of engineering and scientific schools (almost all public). For example, Ecole Polytechique or Ecoles Normales Superieures. In 2006, I have been admitted to ENSIIE (ranked first engineering public school in computer science) and also the Ecole Normale Superieure at Rennes.
