    GATE 2021 Biomedical Engineering Exam Pattern

    GATE 2021 Biomedical Engineering Exam Pattern

    GATE is an all India competitive exams for engineers from various branches. The exam constitutes of 25 papers in GATE. Applicants can appear for only one paper at one time. Candidates are advised to go through GATE 2021 Exam Pattern.

    • GATE is a computer-based test.
    • The exam includes 2 types of question - Multiple Choice Questions (MCQs) and Numerical Answer Type (NAT).
    • No negative marking is there for NAT but it is applicable for MCQs.
    • For 1 mark MCQs, 1/3 marks will be deducted for every wrong answer.
    • For 2 marks MCQs, 2/3 marks will be deducted.
    • The duration of the exam is three hours.

    How to Prepare for GATE 2021 BM Paper?

    GATE 2021 Biomedical Engineering Preparation Tips

    Since Biomedical Engineering is a new addition in GATE examination, here are some Preparation Tips for the assistance of the candidates who are planning to appear for the same:

    1. Set short term goals

    • There should be an organized chart for daily, weekly and monthly targets instead of long term non-realistic goals.
    • Prepare according to that chart only.
    • Focus on major topics first

    2. 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. 

    3. 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.

    4. Put your Practice to Test

    • Take topic wise and overall mock tests to know where you stand in terms of application.
    • Analyze each of your mock tests and rectify the mistakes especially the conceptual ones.

    5. 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. 

    6. Appropriate Information and Awareness

    • Before beginning, to craft, a preparation strategy 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.
