Divide the essay into 3 parts : the intro , the content and the conclusion.
Use powerful , short and dynamic sentences instead of lengthening it too much.
Stick to the given topic and express your views in the best way you can.
Prepare a mind-cloud of the key words you wish to use or words related to the topic as this can reduce the time of thinking for words when you write the actual essay.
Dont rush the essay.Work upto the main content....
