How to Prepare for IES Electrical Engineering Without Coaching?

• Prelims is an MCQ exam which has 2 parts - GS (2 hours and 200 marks) and Subjective(3 hours and 300 marks) (related to your branch).
• Mains is a written based Exam in which there is a paper for different subjects in Electrical Engineering.
• Interview is a third and last stage where your personality is examined as you will become a technical bureaucrat.
  The strategy for all three parts of the exams is different as all are different in nature. The test is taken for 200 marks

PREPARATION STRATEGY FOR PRELIMS:
In the preliminary stage, the best strategy is to revise your concepts and practice a lot. GS is also an important aspect in the prelims because many technical exams doesn't have the GS in their pre exams, so it has to be studied and revised regularly so that you don't forget.
The prelims required a lot of practice and are qualifying in nature hence focus must be to be prepared all around.
Making notes is most important as these are the assets that will come in handy in the end most. In the last remaining months, get some mock test and solve them regularly so that the speed and accuracy is maintained.

PREPARATION STRATEGY FOR THE MAINS:
The Main/Stage-II Examination will consist of two conventional type papers in Engineering Discipline specific with duration of three hours and maximum marks of 600 (300 Marks in each paper). So in the preparation for this part one has to be thorough with all the concepts and proper notes as exam required descriptive notes. The main practice for the exam is
of writing your answers in an effictive manner using diagrams and good citation of the questions and solution.

Some important strategy which can come handy are :
1. Make realistic goals. Try to revise the concepts on the weekly and biweekly basis becuase sometimes students
forget to revise and then they had to study again.
2.Make a daily .to do list which should be balanced with study and practice.
3.Last and most important thing is that practice and practice. Without practice the desired rank cannot be achieved.

SUBJECT SPECIFIC STRATEGY:

1. For subjects like Machines, Drives, Power Electronics and Power System a lot of theory is needed to be covered and numerical to be practised.
2.For subjects like Network, Measurements and Digital one need to practice a lot as concepts are easy but there are a lot of
concepts so regular revision is required here most.
3.For Engineering Mathematics a lot of practice and revision is required.
