GATE is a national level examination which is taken by more than 9 lacs candidates every year for higher education and research opportunities. Cracking such an exam is a challenging task. Highly motivated candidates with a clear vision of their goal will only be able to score well in the exam.

To crack GATE 2020, candidates must have a proper strategic plan. This strategy should be subjective and based on one’s own abilities and limitations. There are many coaching institutes that offer a proper path for the aspirant but it is not the only way to score in the exam. Therefore, we have come up with some essential tips that candidates may follow to ace GATE 2020 without coaching.

GATE 2020 Highlights

  • GATE 2020 will be held in Computer Based mode on February 1, 2, 8 and 9, 2020.
  • IIT Delhi will be the conducting authority of GATE 2020 examination.
  • Biomedical Engineering is a newly added subject in the list of 25 subjects.

GATE 2020 Biomedical Engineering – Preparation Tips 

Since Biomedical Engineering is a new addition for GATE 2020 examination, here are some Preparation Tips and the Detailed Syllabus of the paper for the assistance of the candidates planning to appear for the same:

  • Set short term goals: There should be an organized chart for daily, weekly and monthly targets instead of long term non-realistic goals.
  • A strong conceptual base: As a future biomedical engineer, your capacity to understand scientific and mathematical principles is important. As you explore the fields of math and science in preparation for the exam, challenge yourself and make an extra effort to excel in these fields and not just qualify them. 
  • Constant Revision: Revise what you study on a daily basis instead of piling up and keeping long term revision plans. Frequent revisions save a lot of time and help in building a strong conceptual base. Make charts or notes to keep a track of formulas for last-minute revisions.
  • Put your Practice to Test: Take topic wise and overall mock tests to know where you stand in terms of application. Analyse each of your mock tests and and rectify the mistakes especially the conceptual ones. 
  • Balance is a must: Keep a balance between work and play. This will help in maintaining your interest in the syllabus and level of productivity. Take frequent breaks in the beginning and gradually reduce the frequency of breaks once the concentration ability is all built up. Deal with the preparation process with patience, as shortcuts aren’t the solution.
  • Appropriate Information and Awareness: Before beginning to craft a preparation starategy candidates must be aware of the syllabus and other related information. An organized schedule considering one’s strengths and weaknesses in various topics will have better and long lasting results on the actual performance. The syllabus for GATE 2020 Biomedical Engineering paper is tabulated below:

How to Prepare for GATE 2020 without Coachings?

There are certain factors that the GATE aspirants need to keep in mind while preparing for the exam. We have formulated a few strategies opted by the previous year toppers that candidates may follow to ace the exam.

Start Your Preparation Early

Candidates must start their preparation early by doing so, they will be able to compile all the necessary study material and create a proper plan that they may follow during their course of preparation. Preparing a layout and then working accordingly will cut-shot the time wasted while being confused about how to start their preparation

  • During this phase, candidate must analyze the time required on each subject and divide the number of days that they may give on a particular subject for thorough preparation.
  • Candidate must create a hierarchy of the subjects he/she will cover.
  • Follow what you have planned throughout your preparation phase.

Go through the Syllabus First

Another foremost step that candidates must do is to have a clear idea of GATE Syllabus that needs to be covered. GATE is a high-level exam and therefore, there is vast syllabus that candidates need to cover. In order to cover the overall syllabus without missing any topic, candidates must go through the syllabus provided on the official website of GATE 2020. Candidates must try to cover those topics first from which the possibilities of questions asked are higher.

Tabulated below is the GATE 2020 Syllabus for each stream along with the paper code.

Time Management

Time Management plays a major role while preparing for the exam. GATE aspirants should utilize each second effectively. Proper time division for covering the syllabus, practicing sample papers and last-minute preparation should be done so that the candidate does not miss anything before attempting the paper.

Keep Your Concepts Strong

Having a stronghold on the basics of the topics can help in performing much better in the exam. Candidates must have deeper conceptual knowledge on the frequently asked topics. The easiest way to keep command on basics is: Prepare short notes of formulas, concepts and compile it at a single place. Make it your habit of going through the short notes before starting your preparation each day.

Practice Mock Tests

Mock Tests are the best source for GATE preparation. If taken seriously, it has its own benefits that candidates may get to know while attempting the question paper. Once the candidates have covered all the syllabi, they must take as many mock tests as possible. Mock tests are similar to the final test that candidates will give. One mock test each day will benefit the candidates in the following way:

  • It will enhance a candidate’s problem-solving efficiency.
  • Mock test improves the chances of error.
  • Solving mock tests will give candidates an idea about the type of questions asked frequently.
  • Many times it happens that the questions asked in mock tests come as it is in the question paper.
  • Mock test boost confidence in the GATE aspirant.
