IES Exam Preparation Tips

Plan for six months or a year

Divide the months into distinct subjects and aim to finish the full syllabus in the remaining time. In the present environment with high cut-offs, don’t focus on selective study; instead, read through the entire syllabus since you never know when “the last topic might be the issue of conquest.”

Subject-wise Plan/ Bi-weekly plan

For each topic, the study should be exam-oriented, which means you should familiarise yourself with the subject so you know which areas to concentrate on, whether theory or numerical problems, or simply tackling previous years’ questions would serve. Every topic necessitates a unique method. For example, in mathematics, you may be expected to concentrate on practice problems, but the General Studies Paper necessitates a unique technique. Similarly, the approach to technical subjects may range from one subject to the next. If you’re enrolled in a coaching program, pay attention in class and study hard. Your class notes should be comprehensive and ready to use in the classroom, with simultaneous marking of IMPORTANT concepts/formulae and the development of a habit of putting NOTE points wherever they are needed. If you prepare only via self-study and not through coaching, taking notes is also recommended.

Daily To-Do list /Daily plan

This is mostly for time management purposes. Plan and freeze your study hours, and don’t use your phone, social media, or WhatsApp during those times. It will help you remove unnecessary tasks from your calendar and make the most use of your time for the study if you organize your following day’s agenda in 10 to 15 minutes. I would also recommend that you pre-plan your study area/subject/topic for the next day; this will aid in stimulating your mind’s senses for study, which will aid in greater memory recall. Solving prior years’ GATE & ESE problems (at least from the last 10-15 years) should be done concurrently with class notes. Do not put it off; finish the previous year’s questions first for all of the topics that are discussed in class or that you study on your own.

Make a Revision strategy

Make it a habit to read and revise at the same time. While studying a given subject, dedicate 70-80 percent of your self-study time to developing new subject concepts, and the remaining 20-30 percent to revising previously completed topics/subjects. In the months leading up to the exam, increase the revision time to ensure appropriate idea retention until exam day.

IES/ESS Topper’s Interview



 Is IES more challenging than IAS?

Extensive preparation, mental fortitude, and endurance are required for both UPSC and IAS tests. Students with a background in engineering, on the other hand, will find IES to be significantly simpler and may even benefit from it in work. The IES is regarded as a technical test, and passing it may need just degree knowledge.

What is the minimum age requirement for the UPSC IES/ESE 2022 exam?

On January 1, 2022, he must be at least 21 years old and no older than 30. To be eligible, they had to be born between January 2, 1992, and January 1, 2001.

How many IES Exam tries can a student make?

The number of times a candidate can take the IES test is unlimited. Candidates can take the IES Exam until they reach the Union Public Services Commission’s maximum age restriction.

There is no doubt in the fact that India has produced world-class engineers through its dynamic education system. Despite huge salary packages being offered in private companies, individuals aspire to work in government departments and companies. With job security, and a desire to serve the nation and earn respect, this inclination has led to students opting for the IES exam day by day.
