Hi Ayushi,

Memorizing things is not the correct way to study. It's good to know that you are good in mathematics. But, if you are interested in doing medicines, you can choose the field. Also, remember that if you take biology, you will have to learn not only about humans, but plants and animals as well. Learning and understanding helps you remember things better than memorizing.

But if you are good in solving maths, you can choose engineering as maths is very important subject in this field. But, final decision is upon you, depending upon what you like and where you want to make your career.

Best of luck!
