How to Prepare for GATE TF Paper?
How to Prepare for GATE 2021 TF Paper?
Sometimes most of the candidates forget to incorporate some of the important points in their preparation plan or sometimes it is difficult for candidates to find the right starting point. For all those candidates we have prepared a few preparation tips that will them in building a good preparation strategy. And the first and foremost preparation tip is to know your syllabus and exam pattern which is mentioned above in detail. After reading that candidates can have a look at some of the best preparation tips:
1. Short and Long Term Study Plan
Candidates can divide their preparation plan as short term and long term study plan. The implementation of any of the plans is totally based on the choice and comfort of candidates.
- In short term study plan: Candidates can include revision, practice previous year papers, taking the mock tests, etc after the completion of each major topic. This will help them in judging their weaker and stronger points at an early stage of preparations. Candidates can also predict their rank using GATE Rank Predictor
- In long term study plan: Candidates can go for final revision, mock test, online test, etc only once that is after the completion of the whole syllabus.
2. Division of Time
We have created a time table for you by taking into consideration that most of the candidates spend an average of 5-6 hours daily to prepare for the exam.
|Time Allotment||Activities to Do|
|5:00 AM to 8:00 AM||Pen down the important topics and scan all the important points|
|8:00 AM to 10:00 AM||Take a Break|
|10:00 AM to 1:00 PM||Pick up a Major Topic|
|1:00 PM to 5:00 PM||Take a Break|
|6:00 PM to 9:00 PM||Go through all the topics that you have covered in the day or you can also continue with the preparation of Major Topic|
|10:00 PM||A quick go through of the Notes and try to sleep early|
3. Cover the Basics and Maintain Consistency
- Candidates are advised to start from the basic concepts. Make your base strong enough so that you can cover the difficult topics easily.
- Consistency plays an important role in your preparation. Without it, you will not be able to achieve any of your goals. Stick to your time table and first go for the major topics only.
4. Online Test, Mock Test Series, and Video Lectures
Taking the online tests or mock test is one of the important steps of your preparation plan. The mock test will help you boost up your confidence level as it gives the feel of the real exam. With the help of an online test, you will be able to judge your strong and week points and you can prepare for your weaker sections again. Candidates can also take help from video lectures. The benefits of video lectures are:
- Easy to access anytime or anywhere.
- Learning at one place.
- Chances of getting valuable information.
- Information about an easy approach to difficult topics.
5. Previous Years Practice Papers
- Previous years' papers are handy and you can go through them n number of times.
- You can observe the trend of questions asked in the past 2-3 years and prepare according to that.
- Practice papers help you prepare for your exams in the long run.
