• For admissions to many Indian universities and professional courses, students are typically required to obtain an AIU (Association of Indian Universities) Equivalence Certificate that certifies the qualification is equivalent to Indian Class 12.  authorities may not process a foreign-board qualification.  counselling and admission rounds begin.  makes the qualification acceptable for admission processing.
