How to Prepare for GATE EC Paper?
Preparation Tips for GATE 2021 Electronics and Communication Engineering Paper
1. Division of Syllabus
- Candidates should divide their syllabus based on priority. There are various factors to set the priority like on the basis of difficulty level, on the basis of weightage of marks, etc.
- With a proper division of syllabus, it will become easy to cover the syllabus in a particular period of time.
- The main motive to divide the topics or sections is that you can easily complete the syllabus when divided into small portions.
2. Set Right Targets
- Candidates must set some targets. For example, you can set a target that I will complete 6 topics in a particular week. This is also called a target based study plan and when you fulfill one target then it gives you a feeling of achievement which in return boost your level of confidence.
- Do not overburden yourself and set up easy targets.
3. Time Divison
|Time Allotment||Activities to Do|
|5:00 AM to 8:00 AM||Revision Time|
|8:00 AM to 10:00 AM||Take a Break|
|10:00 AM to 1:00 PM||Start new Topic|
|1:00 PM to 5:00 PM||Take a Break|
|6:00 PM to 9:00 PM||Complete the remaining topic|
|10:00 PM||Again go through your Notes|
4. Practice Papers
- Practice papers will help you in getting an idea about the exam pattern, type of questions asked the paper, difficulty level of questions, weightage given to topics or sections, etc.
- You can also improve your speed and accuracy.
- Candidates should practice 1-2 papers in every 3-4 days.
- Do not get demotivated if you are not able to solve the questions. Observe your weaker areas and try to work on them.
5. Confidence and Motivation
- Keep yourself motivated and believe in yourself.
- Do not compare yourself with your friends. Focus on your preparations.
- Try to avoid distractions like T.V, social media, etc.
- Take frequent breaks for relaxation and keep up the good health.
