Why is the knowledge of Exam Pattern important?

GATE is taken by thousands of students from all over India to apply for admissions to the best postgraduate programs and top career opportunities. Biomedical Engineering has been offered for the first time as a UG course in IIT Hyderabad. This will serve as a model for other IITs and provide a good base for students looking to pursue M.Tech in Biomedical Engineering. 

This is an emerging discipline with a lot of scope and GATE has introduced changes to this paper for the first time in 2020, owing to the very high difficulty level. The pass percentage earlier was only 15-17%. As the paper pattern has changed, students will need to go through the revised paper pattern to understand how to answer it best. 

The paper pattern shows the duration of the test, the type and number of questions to be answered throughout the syllabus, the weightage of each section, and the marks assigned to each subject to be evaluated. Therefore, awareness of the paper pattern will be very useful, since you can organize your study time according to the allocated marks for each topic and section.

What is Biomedical Engineering and its scope?

Biomedical Engineering, also known as Bioengineering, BioMed or BME is a multidisciplinary STEM field integrating biology and engineering, applying the concepts and materials of engineering to medicine and healthcare. Biomedical Engineers' growing demand is related to the general change of society towards the regular use of machinery and technology in all facets of life. The synthesis of engineering principles and biological understanding to meet medical needs has helped create innovative, life-saving ideas such as:

  • Artificial organs

  • Surgical robots

  • Advanced prosthetics

  • New therapeutic drugs

  • Kidney dialysis

Biomedical Engineering is a wide field with various focus areas and depending on the details of your job, the exact nature of the work you will find yourself doing will vary. A few examples of some of the Biomedical Engineering subdivisions include:

  • Biomedical Electronics

  • Biomaterials

  • Computational Biology

  • Cellular, Tissue and Genetic Engineering

  • Medical Imaging

  • Orthopaedic Bioengineering

  • Bionanotechnology

Scope after GATE 2021 BM Paper

The number of students answering GATE in Biomedical Engineering (BM) is rising high because it is a new addition. The Master's courses now need a GATE score and several companies are using GATE scores for recruitment as well. Some students will be interested in pursuing M.Tech from IITs / NITs in different streams while others will attempt to get a job. Therefore, it is important to understand the importance of the GATE BM exam and the various opportunities it provides through GATE.

Study M.Tech after GATE

  • The most common way to proceed is to apply for M.Tech at the IITs, IISc, and NITs after having cleared the GATE exam.
  • It can be a very significant step for students who have dreamt of studying at the country's top institutes such as IITs and NITs.
  • You will also be eligible for the MHRD stipend during the two year Master's course, provided you have a high GATE ranking.
  • Also, if you apply to other states, regional, or private colleges that do not have GATE scores as their primary selection criterion, getting a good GATE score will still give you an advantage over the other applicants. Once you have completed M.Tech, you can apply to private jobs that provide good salary packages for biomedical engineers.  Know More GATE Counselling 

Job opportunities

  • Healthcare manufacturing, pharmaceuticals, and healthcare service sectors are the main recruiters.
  • Government agencies such as the Department of Drugs and state-wise health departments also recruit B.E./B.Tech graduates in Biomedical Engineering.
  • In general, the average starting salary is between INR 3,00,00 - INR 6,00,000 per year.  Check PSU Recruitment through GATE

Research opportunities

Research is a field where the biomedical engineers in the country can thrive and succeed. However, many students either apply for M.Tech or take up government or private jobs. Those of you who are more inspired to explore the possibilities of biomedical research can choose a career that is research-oriented and give back to society.

Note: –  There is no Public Sector Undertaking (PSU) for the biomedical engineering field. These companies do not hire biomedical engineering graduates because they do not manufacture medical devices.
