STUDY TIPS
To crack the IES (UPSC Engineering Services Exam), follow a well-structured preparation plan that emphasizes complete syllabus coverage, regular practice through previous year questions (PYQs) and mock tests, and effective time management. Make concise revision notes, stay updated with relevant current affairs, and maintain a healthy, stress-free routine. Begin preparation early, understand the exam pattern thoroughly, focus on weak areas, and strike a balance between conceptual clarity and speed, especially for numerical problem-solving.
1. Reading Habit - Allocate some time every day to read newspapers, current affairs magazines, and various books for engineering subjects. Keep yourself updated with all important events and issues of the last six months.
2. Clear Your Basics - Make sure to clear all the basics of each topic first.
3. Prepare Self Notes - Try to make your own notes which will help you to revise quickly. If not possible try to highlight the key points
4. Practice Formulas - All the formulas should be at your fingertips. Practice them regularly so that you do not forget them.
5. Solve Examples - Examples must be solved first in your preparation.
6. Practice Papers- You must practice diligently and be in a position to answer any type of questions asked from any topic.
7. Examine the Mock Test - Mock Test are not only for the purpose of solving but also for analysing and examining so not to repeat the same mistake again.
8. Know Your Strong & Weak Areas - By analysing and solving mock tests find your weak and strong areas. Give more time to weak areas.
