General ability test:
The candidate?s comprehension and understanding of General English
shall be tested through simple exercises. Questions on knowledge of current
events and of such matter of everyday observation and experience in their
scientific aspects as may be expected of an educated person. Questions will also
be included on events and developments in Telecommunications, History of India
and Geography. These will be of a nature, which can be answered without special
study by an educated person.
