 However, specific field entrance exams that are required for admission to many institutions are notorious for their inconsistencies, with courses which for instance may traditionally require mathematics, physics or chemistry entrance exams, allowing non-related entrance exams to catch a large number of underachieving applicants who otherwise would not be admitted, and do not have a place at more selective institutions in the same field.For the other side, higher grades inside the higher education institutions were more frequent for those students of private, public polytechnic and some public university courses that were globally the worst pre-higher education applicants.This implied a long-lasting reputation of lower teaching standards and easier entrance requirements in many public polytechnic and private institutions, as well as in some public university departments, which seemed rather relaxed.
