Read the question properly. if question already give the name, event, venue and date, just follow them, cuz if din follow, marks will be deduct. try to use all the words given, and make sure nt to make grammar mistakes. try to fit some idioms in each paragraph. ( usually can use something like as happy as a lark, cuz they often like to give question on helping ppl). nt to write too long in each paragraph, 3 to 6 sentences will be sufficient enough.
