Other competitive study abroad examinations include the MCAT and the LSAT, mandatory for getting into medicine and law respectively in the USA. The MCAT is a multiple-choice test that is designed to evaluate the examinee's aptitude and knowledge about relevant subjects, while the LSAT that is administered by the Law School Admission Council for students who wish to pursue a career in law in the USA, Australia and Canada.

TOEFL vs IELTS

The TOEFL and the IELTS probably top the list with regard to the sheer number of students across the world needing to undertake one or the other to demonstrate English language proficiency. The widest possible selection of universities and colleges accept TOEFL scores, including the top 100 in the UK, U.S, Canada, Australia and New Zealand. The IELTS is a mandatory exam for Indian and other non-native English speakers, especially in the Commonwealth countries, for entry into most reputed universities and colleges overseas, and occasionally for immigration requirements as well
