 Standard
The standard of the papers in Elementary Mathematics will be of Matriculation level.
The standard of papers in other subjects will approximately be such as may be expected of a graduate of an Indian University.
 Syllabus
 English (Code No. 01)
The question paper will be designed to test the candidates’ understanding of English and workmanlike use of words.

 Intelligence and personality test
In addition to the interview the candidates will be put to Intelligence Tests both verbal and nonverbal, designed to assess their basic intelligence. They will also be put to Group Tests such as group discussions, group planning, outdoor group tasks, and asked to give brief lectures on specified subjects. All these tests are intended to judge the mental calibre of a candidate. In broad terms, this is really an assessment of not only his intellectual qualities but also his social traits and interests in current affairs.
