YoungBuzz Counselor - Hi Pakhi,
You will definitely have to take Physics, Chemistry and Biology in your 11th and 12th standards if you want to appear for the MBBS entrance exams. In addition, you can take Mathematics as well so that you have more options after your 12th standard in case you change your mind. Hope this helps.
Please revert back with further questions and feedback.
Wish you all the best!
