Not this is possibly the most intricate part of the exams so you must follow the plan to the letter.
Do all the modules and go through the practice writing exercises at the end.
But before you start, what’s your opinion of writing in general?
Do you like it?
Do you get to write very much?
Do you write emails in English?
What part of writing do you not enjoy at all?
Drop this information in the comment section and I will get back to you.
Thanks very much and good luck.
