For an average good student, one year of preparation is enough to have satisfactory performance in the CSE. The regularity of balanced study must be maintained throughout this period of preparation.

For Preliminary Exam., one should go for much extensive studies and should not confine to some specific areas of study as the question may be asked about just ANYTHING in one or the other ways. So a correlative approach is a requisite.

For Main Exam., first of all, the candidate should decide the areas of emphasis and elimination depending upon the analysis of the trend of questions being asked during the last 5 years.

For Interview, the candidate should associate himself with a group having a positive attitude and logical thinking. The candidate should discuss at least one National/International issue daily to access different views. Then the candidate must analyses all the points for reaching a satisfactory conclusion. The mock interviews have also proved to be very helpful.
