Dear i was worried like you last year. I had a same problem coz i thought tht writing an essay around 3000 words would be a hard target but i just took pen started writing different essays n got 49 in essay. However, at the time of attempting paper i did a lot of mistakes. But became fortunate to get avg marks...........So, untill and unless you don't try to write an essay you will not be able to resolve your essay writing problem
