Höstterminen 2002 började ca. 1000 studenter på något av LTH:s civilingenjörsprogram. Ett år senare hade 300 av dessa studenter missat studiemedelsgränsen. Denna artikel redovisar studieresultatet för de studenter som började läsa till civilingenjör på LTH förra hösten. Det visar sig att studieresultatet för de olika programmen skiljer sig åt väldigt mycket. Det finns inte heller någon större korr
