Hello Rupak,
          You have interest in Physics and biology so you can appear to NEET and can become doctor. Also you can do B.Sc in various subjects like biotechnology and microbiology and many other. Prefer the career path which you love the most. After all all the best for your career.

Scope for Biomedical engineering in India is far below compared to it's scope in many developed countries. The core Jobs available after bachelor's degree are very few. It is because that no company manufactures biomedical equipments in India from scratch. Most of the equipments are imported and few equipments are assembled in India. So there is less scope for R&D jobs right now. But it may get improved in near future as healthcare industry has got a greater demand as the population and healthy consiousness increases.

There are plenty of jobs for service and sales engineers. But there is also a problem. To get that job you need not to be a biomedical engineer. Any engineer with ece/eee/instrumentation degree are eligible along with biomedical engineer. Sometimes they prefer ece/EEE/instrumentation engineer as they are more exposed to electronics. However if you managed to get a job service/sales job it involves a lot of traveling and the pay is very less in the beginning.

If you want to pursue higher studies then there is an average scope. Few IITs provide Mtech and PhD degrees especially in biomedical field.

All the best

Hey Lakshmi.

Biomedical Engineering is the confluence of engineering, technology and biological sciences to improve the quality of healthcare, medicine and human life. Biomedical engineers and scientists are responsible for developing, designing and improving medical devices and procedures for efficient diagnosis, operation and treatment of diseases and other health ailments. Some examples of Biomedical Engineering innovations are artificial limbs, prosthetics, imaging machines and various other medical devices.
Biomedical Engineering is still in the development stage in India and, therefore, scope is very limited for this field. One of the main reasons why progress is slow is due to the lack of integration between research institutions, hospitals and universities in India. In developed nations such as USA, UK and Singapore, excellent integration exists between universities and hospitals, thereby creating the perfect environment for R&D in Biomedical Engineering. In India, most of the jobs related to Biomedical Engineering are in non-tech areas such as service, maintenance, customer support, sales and management. Students interested in pursuing a career in research and core development work in Biomedical Engineering must look for jobs in universities, labs and research centers in India or pursue MS and PhD studies in USA, UK and other nations.
Following is a list of top institutes that offer this course at the undergraduate level in India:

NIT, Raipur
NIT, Rourkela
TSEC, Mumbai
DJ Sanghvi College of Engineering, Mumbai
GEC, Gujarat
SSN College of Engineering - Anna University
BMS College of Engineering, Bangalore
VIT, Vellore
Manipal Institute of Technology, Bangalore
Bharati Vidyapeeth, Pune
BMS College of Engineering, Bangalore
MS Ramaiah Institute of Technology, Bangalore
Many universities in India offer MTech and PhD degrees in Biomedical Engineering. Considering how limited job opportunities are for this field in India, it is very important for aspiring biomedical engineering students to do their graduate studies from reputed universities such as the following:


IIT Bombay (MTech and PhD)
IIT BHU - MTech only
IIT Hyderabad (MTech and PhD)
IIT Kanpur (MTech and PhD)
IIT Kharagpur (MTech in Medical Imaging and Image Analysis)
IIT Madras (MTech in Applied Mechanics with specialization in Biomedical Engineering)
IISc, Bangalore (Interdisciplinary PhD in Bioengineering)
MNIT, Allahabad (MTech only)
NIT, Rourkela (MTech & PhD)
Manipal Institute of Technology (MTech in Biomedical Engineering)
COEP (MTech in Biomedical Instrumentation)
SCTIMST, Trivandrum (MS & PhD in Bioengineering - affiliated programme of SCTIMST offered at CMC, Vellore)
SCTIMST, Trivandrum (PhD in Biomedical Devices Technology - Joint programme of SCTIMST, CMC and IIT Madras)

Companies in India:

L&T
General Electric Global Research, Bangalore
Stryker Global Technology Center
Deloitte Consulting India Pvt Ltd
Texas Instruments Inc.
Phillips Healthcare
Orbees Medical
Siemens
Covidien


Hope this helps. All the best.
