As you want to be good in presentation so as I will suggest that whenever you are writing answer it should be very exact that means the answer should be to the point. Answer should not seem fake. The content of the answer should be exactly match with the answer.

Don't write so a lot of thing in one answer.
Whatever the question asking after reading the question you just answers that.
No need to write so various thing to just to increase the length of the answer. Write the answer properly.

It will be easier who is checking your answer if you write the answer to the point wise. Just underline the important lines in your answer. So that the examiner can easily understand what you are trying to say in the answer.

According to me if you go after in this way to write your answer then from the next time you will get good marks surely..
