How to Write Better

This is one of the most difficult skills and many students feel unconfortable by writing as they think it's a problem of being like an artist or having imagination or  having a gift, a toke. It's not so; most of it is just working and working on that. Here you are a link with good advice: click here
But the best way to improve your writing for an exam is following these simple steps:

1. Read carefully what you are asked to do to avoid getting out of the topic. Check the topic from time to time to get stuck to it.
2. Make a list, a diagram or a map of you ideas to organise your writing and remember it should be something like this:
• introduction: say what topic you are going to talk about. (2-3 lines)
• main paragraph: with the most general and important ideas (5-7 lines)
• secondary paragraph(s): secondary ideas or examples; you could introduce your personal point of view here. (5-7 lines but not longer than the main paragrph)
• conclusion: write a long sentence to summarize what you've explainded before. It should be different to the introduction but connected to it (2-3 lines)
