Knowing the syllabus of the exam is the first thing to do for the preparation. The Union Public Service Commission conducts the Civil Service Examination for selection into the IAS, IPS, IFS, IRS, and other allied services.

This CSE exam is conducted in three phases – preliminary, main, interview. All applicants first face the prelims exam and majority of them get eliminated at this stage itself. Given the low pass through rate of this stage, it is important to prepare for the UPSC prelims exam in a holistic manner.
