It's admirable that you are holding onto your dream of becoming a general surgeon! While your 10th board percentage might not be ideal, it doesn't necessarily have to be a roadblock.

Have an open and honest conversation with your parents. Explain your passion for becoming a general surgeon and explore options together.

If possible, see if you can convince your school to allow you to switch streams to Science in 11th and 12th grade. This would give you the necessary foundation in Biology, Chemistry, and Physics required for medical school entrance exams.

Numerous online resources offer courses and materials for Science subjects relevant to medical school entrance exams.

Consider enrolling in correspondence courses offered by universities or private institutions to learn the required science subjects at your own pace.

If switching streams isn't feasible, consider a Bachelor of Science degree in Biology or Zoology. This will provide a strong foundation in life sciences. Degrees like Biotechnology, Microbiology, or Nursing can also be stepping stones, although they might require additional preparatory courses for medical school entrance exams.

Focus on the National Eligibility cum Entrance Test (NEET) - the all-India entrance exam for medical colleges. Start preparing early and utilize resources like coaching institutes, reference books, and mock tests. Some universities in India offer Science programs through open or distance learning modes. This could be an option if a regular degree program isn't feasible.

With dedication and the right approach, you can still achieve your dream of becoming a general surgeon!

I hope it helps!
