Government & Defence Entrance Exam

Public Administration is the best subject for IAS because where you learn that to do well in future, help in interview,small syllabus, GS support & better from previous performs.

All type of graduates are eligible to appear for Civil Services Examination. As Civil Services Examination is the most competitive examination of India, lot of IAS aspirants do B.Tech before appearing for Civil Services Examination so that they have a good standby career option available if they are unable to crack Civil Services Examination. Therefore, I am of the opinion that you decision of doing B.Tech is a right decision.
