Hey student,

Give equal weightage to all subjects. But when it comes for Biology, give your all efforts. Because the content of Biology subject of 11th and 12th science is just beginning or you can say it's a kind of basics for your future Microbiology subject. Give your best to the chapters of Haematology and Immunology in 11th and 12th science, because in Microbiology this both are very basic as well as very important subjects which you'll learn in 11th and 12th science.

All the best student,

Hope this helps you.
