I had my chemistry exam yesterday. I was supposed to attend 15 question but I did 18 qns. But worst part is that my answer to last qn were correct but the answer to some qn that appear before attempting 15 qn are incorrect. Now checker will deduct mark for which one?

I m 11th grade student of science faculty and i am physical group😃 student. Boards are near. So can someone suggest me about how I should study. I want to get really good grades.
