What to do in your essay

• We should write concisely (briefly + precisely). It means we do not use phrases like: "As it was said in the previous part...", "as it has been already mentioned" and the like.
• We use formal writing style: active or passive voice, present tense and no pronouns like "you" or "we".
• We make sure our reader understands EXACTLY where our own ideas are stated and where we introduce someone else's thoughts and ideas by citing clearly (one in-text reference in the end of the paragraph is NOT enough because it is not clear which ideas in that paragraph were yours and which were not). We do it by citing for somebody's ideas AND using hedging language for our own ideas and evaluation.
• Instead of using words that add value (e.g. interesting, nice, important) we use expressions that might be supported by further evidence: e.g. majority, the alternative idea (issue/problem/notion).
• Each paragraph has to contain a topic sentence (main idea), which is supported by some evidence. It would be an advantage if you provide an example/some data that would be consistent with this idea/argument.
