You have an attribute and capacity to take things to logical conclusion and this aspect will help you in the long run.

As per your chart, yes, you could enter the medical field and become a doctor, but that would require your complete and whole hearted dedication and hard work without which the destiny doesn't play a role.

You should start performing meditation in the early mornings on a regular basis to develop the abilities to focus and concentration for longer durations, this would help you in a good way to achieve your objective of preparing and studying for the exams.

Best Wishes.
