How to Prepare For Biomedical Engineering?

Your preparation for GATE 2021 should be done in a planned manner. Biomedical Engineering is a new subject so you should prepare more rigorously. The first step in any exam preparation is to go through the exam pattern and syllabus carefully. Next, you have to build a good strategy that will be your blueprint for your preparation. Make a study time-table that will keep your preparation in check. Follow the strategy and the study time-table sincerely. We have discussed important steps and tips below that you can go through and keep in mind during your preparation.

Concept Clarity  

When you prepare a particular topic, make sure that you understand it well. Concept clarity is really important in sections like Mathematics. If your basics are weak then you will lose marks even in the scoring question. That can cost you a lot in the exam. So be sure that your foundation is strong enough that you can tackle even the tricky questions.

Prepare for Each Section

General Aptitude

  • It’s weightage along with Mathematics is around 15%. This section can be scoring if you have prepared well enough.
  • You have to prepare on a daily basis for general aptitude as the sections tests your verbal and numerical aptitude which cannot be gained in a day. 
  • Solve at least 10 aptitude questions so that you don’t get the burden of practicing it all in just a few days. 
  • Start preparing for this section from the beginning.

Mathematics

  • This section is comparatively vast than others. Prepare for this section topic-wise. Distribute your preparations in small parts so that it can be completed easily. 
  • Practice is the only way that will help you score in Mathematics. Practice as much as you can ad try questions of all difficulty levels. 

Subject-wise questions

  • The subject-wise questions will be of more weightage compared to others. You have to be familiar with all the topics of Biomedical Engineering and prepare them well.
  • Complete the easy topics and the topics with more weightage first. Pay more time and attention to the topics that you are weak in. 
  • Make running notes while preparing for the topics. Make them short and precise. These notes will come in handy during your revision. 

Complete the syllabus

Try to complete the preparation of the entire syllabus in 4-5 months. That means if you start preparing from now then your preparation should be over by the end of November. Try not to leave any topic or subtopic in the syllabus. If you feel that you won’t be able to complete your syllabus by November then it means you have to work on your speed and accuracy. Both the factors are important not only during the examination but also during your preparation for GATE 2020. 

Practice Mocks

After you have completed your preparation, you should move on to solving the mock tests or online test series. Our toppers suggest taking weekly mocks, topic-wise mocks and monthly mocks. This will help you to continuously monitor your preparation. The topic-wise mocks will help you in detecting the weak topics that you have to work on more. Weekly and monthly mocks will keep you aware of the speed of your preparation and will help you practice time management. Also, practice previous year question papers a lot. Take the last 5 years’ question papers. Practicing them will give you a fair idea about what types of questions have been coming over the last few years. Analyze the pattern of the exam and prepare accordingly.

Do Revision 

Assuming that you have completed your preparation by November, the last two months will be solely for your revision. Revise all the important topics and mock tests that you took. You can also take help from the notes that you made during preparation. It is practically impossible to revise each and every topic in depth. Notes will make it easier for you to revise all the important topics in short. 

Books for Preparation

Your preparation should be done from trusted sources only. Pick up books from renowned authors and publications. Try to study several books and prepare from them well. You can also take help from the study material available online like test series and sample papers, etc. For more study material, you can take the help of the study materials provided by good coaching centers. We have suggested a few books for your GATE 2020 Preparation. You can have a look at them below.

What is Biomedical Engineering?

Biomedical Engineering (BM) merges the application of both principles of Engineering and design concepts of medicine for healthcare purposes. In the Biomedical field, researchers with expertise in diverse areas, work towards creating products and techniques for better health care. It covers the gap between these two fields by mixing the skills of an engineer with that of the medical-biological sciences to achieve advance healthcare treatment. Biomedical Engineering has been emerging as an individual discipline. It is considered one of the youngest disciplines in engineering and has made noticeable progress over the last four years. Most of the work in BM includes research and development, enveloping a broad array of fields.

M.Tech understudies have to be do a significant sum of course work within the to begin with two semesters to complement their UG or Master’s level of instruction. In the third semester, students do M.Tech project although some courses might be taken during that period. In the fourth semester, students work towards the completion of the project. The curriculum is designed in a way to provide a background of Biomedical Engineering along with more specific knowledge in the area of student’s choice. Electives taken during the last two semesters impart specialized knowledge in the area of the student’s interest.
