How am I able to make my written Spanish composition stand out from the rest, if I want to achieve that 7 grade?

Without a doubt, one of the key components of a top composition for Higher or Standard level IB Spanish is that the candidate is able to find a natural, fluid balance between the content and argument of his or her essay. What this means, essentially, is that the points that the candidate is trying to make (which wholly depend on the essay's subject) are complemented, and not hindered by the language that they use. For example, if one is writing about the great potential of renewable energy in the modern world, a good essay structure and solid points of argument can be undermined by misused Spanish idioms, recurring grammatical mistakes, or careless spelling errors.

Similarly, 'playing it safe', or in other words not taking any risks when writing a composition in order to minimise the chances of making mistakes, is also unlikely to persuade the examiner to mark the essay higher than a low-level 6. Whilst the candidate's content in this instance may be more or less flawless, if their argument is not persuasive enough, and if their language is relatively uncomplicated (i.e. constant use of present tense, repetition of adjectives) then the fluency of the essay as a whole is compromised.
