Evaluate and assess their work, different institutions and colleges around the world employ various methodologies and standards. It is challenging to place all the students entering one level from multiple educational systems because these marking methods vary even among colleges in the same nation. Entrance tests help level the playing field for all students so that everyone can see how each one does in verbal and mathematical analyses. As a result, practically all prestigious colleges need the SAT/ACT for bachelor’s programmes, the GRE for technical Master's degrees, and the GMAT for Postgraduate Management programmes. Many university selection procedures begin with these admission exams, though they are occasionally taken in addition to earlier accomplishments.

Students are expected to produce confirmation of English competence in Reading, Writing, Listening, and Speaking through either IELTS/TOEFL/PTE because the education they wish to pursue is in a nation where English is the native language or at least the language of instruction.
