Hi Sagnik
Let me tell you if you have intrest in both it means you should think deeply about it .In your undergraduates you will have to solve real life problems.Like if you opt for medical taking biology you will have to work in hospital ,look after patient and do the checkups or if you opt physics you may have to work for either machine design, design and develop electronics devices or you may have to work in the construction of bridges,roads etc.
So thnk practically which kind of work you want to do.Be clear before th final exam so that without any disturbance in your mind you can choose your degree program.
All the best.
