IIT Kharagpur has released GATE 2022 Biomedical Engineering Syllabus online on the official website. No new changes have been made to the syllabus. GATE 2022 Biomedical Engineering Syllabus is divided into ten sections. With the revision in GATE 2022 Biomedical Engineering Syllabus last year, topics such as stability analysis, time domain, frequency domain analysis, etc. had been removed from the core subject. For GATE Biomedical Engineering, the core subject carries 72% weightage. However, the sections of Engineering Mathematics and General Aptitude carry 13% and 15% weightage respectively. The candidates who choose Biomedical Engineering as their first paper can choose one among Biotechnology (BT), Electronics and Communication Engineering (EC), Instrumentation Engineering (IN) or Life Sciences (XL) as their second papers.

GATE BM Preparation

GATE 2022 Biomedical Engineering (BM) Preparation

The aspirants of GATE 2022 Biomedical Engineering are advised to go through the following section and avail the benefits of the same. Since Biomedical Engineering is a one of the recent additions in GATE, here are some Preparation Tips for the assistance of the candidates who are 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.
    • Prepare according to that chart only.
    • Focus on major topics first
  • 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.
    • Analyze each of your mock tests and rectify the mistakes, especially the conceptual ones. Download GATE Practice Paper
  • 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 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.
