Comparison between IES 2016 and 2017 syllabus for Electrical Engineering(EE).
You are here to know the
“Syllabus diff between electrical IES 16 and 17, new added papers in ese 2017 in electrical engineering, Difference between IES 2016 and 2017 syllabus, New topic added in ESE 2017, removed topic from ESE Syllabus, ”
Every person knows about the changes in the general studies paper (Paper 1) but they might not be aware about the changes about the technical papers. There are major changes in the technical paper also. Here with the help of different colours we try to highlight the main differences in between what has been added and removed totally in IES ESE syllabus.
RED colours: Content which has to study for IES 2016 only and completely removed from 2017 onward.
BLUE colours: Content which is newly added in IES 2017 SYLLABUS.
