The difference between the UG and PG ICAR Exam is nothing but that it is for two different set of students, the UG Exam also also known as the Under Graduate Exam is for candidates who have finished their 12th and the PG Exam also known as the Post Graduate Exam is for candidates who have completed their graduation and are interested in pursuing their Master's  Degree.
