Your aptitude and interests are divided into four categories by the Psychometric Stream Selector career test: mathematics, biology, commerce, and humanities (arts). After that, it ranks them from 1 to 4, where 1 is the most advantageous and 4 is the least. Additionally, based on the RIASEC theory, the Stream Selector assesses your interest as well as your verbal, numerical, clerical, spatial, and reasoning skills. There are 100 objective questions on the test, 60 of which gauge interest and 40 of which gauge aptitude in different fields. Approximately one hour is needed to finish the test.
