Pass an exam

Hi, people!
I haven't written a  notebook for a long time and I need to star again, because I didn't pass the writing exam and I have  another(sounds better) opportunity in September.
I have searched for information about tips for improving my written english so that I can pass that exam.
For instance, I shouldn't be nervous and I should begin  brainstorming. Don't use the dictionary a lot, only for spelling; and practice, practice and more practice.
On the other hand, a common trouble is that Spanish speakers try to write english by translating word per word, but it's better to read a lot and  use several adverbs, adjectives and connectors (or transition phrases). This way you can write? your text longer than before. (I don't understand what you mean here)
To sum up, these are the most relevant tips about writing texts I have read.

Anna, feel free to contact me if you want to practice your written english. I'd suggest reading articles online to see english structures used in context. Additionally, completing some advanced grammar exercises might be beneficial. Good luck!
