4. Key Tips for GATE 2018 Preparation
4.1 Understand the Syllabus Thoroughly
Before starting your preparation, go through the entire syllabus to identify important topics and areas that require more focus. Ensure that your study plan aligns with the topics that are most frequently tested in the exam.
4.2 Create a Structured Study Plan
Plan your preparation in phases, setting short-term and long-term goals. Divide your time between theoretical learning and problem-solving practice. Stick to your schedule and regularly evaluate your progress.
4.3 Practice Previous Year Papers
Solving previous year papers helps in understanding the exam pattern, frequently asked questions, and time management. It also gives an insight into the level of difficulty of the exam.
4.4 Refer to Standard Textbooks
Stick to textbooks that cover the fundamental concepts thoroughly, such as:
- “Engineering Mechanics” by S. Timoshenko
