respected sir/madam i am currently pursueing my engineering in electronics and communication.i have decided to take up ias as my career.since i am from engineering background i want to take up physics and electrical engineering as my optionals.i can manage with physics.i am in doubt that electrical engineering as a subject is very vast.it is very difficult to master it and score good marks in upsc inspite of having the same background.i find few topics are easy and many topics are tough.could please you suggest me what i should do.take up.electrical engineering as an optionals or a theory subject like public administration.i tink public administration is easy to study than electrical engineering.also there are very very institutes which offer coaching for electrical engineering.
