Preparation and Coaching of IFS

The IFS being among the most prestigious services of the country, the competition for examination is quite tough and needs meticulous preparation. So far as optional subjects are concerned, most of the students are expected to do well.

It, therefore, requires systematic planned study with added emphasis on both the compulsory subjects which are usually neglected during the academic examinations.

To have a sound base in the General Knowledge paper the candidates must refer to a basic and standard general knowledge book like “General Knowledge Refresher” by O.P. Khanna, regularly supported by “The Competition Master”.

In depth study of all important aspects of general interest as well as brushing-up of optional subjects offered in the written examination is required. Thorough self-appraisal is also an effective way of preparing for the interview.

There are certain private institutions/agencies imparting coaching and guidance for IFS examination as well as personal interview. By taking due precautions for not falling into unscrupulous hands, coaching from a reputed institution will go a long way to help the fresh candidates to do well in this examination.
