Hi, I am thinking about applying to an Australian graduate program of Actuarial Science (or Actuarial Practice or similar). My GPA is 3 out of 4 in the American system (A, B, C, D, F, etc), how does this score correspond to the Australian system? Here are a few programs I am thinking about, with their entry requirements normally at around 5 out of 7 or 65% in the Australian system: http://programsandcourses.anu.edu.au/program/7420XMACTP http://courses.mq.edu.au/international/postgraduate/master/master-of-actuarial-practice https://www.business.unsw.edu.au/degrees-courses/postgraduate/masters/actuarial-studies#Entry-requirements https://www.study.monash/courses/find-a-course/2018/actuarial-studies-b6014#entry-requirements-2 Do you think my GPA can fulfill this overall requirement? Also, my GPA in the first two years was very very high, but in the last two years, it dropped quite a lot, for a variety of reasons combined. What should/can I do now, since I only have one semester left? Best and thank you all in advance, GPRW
