Hi Jose,
Great question! Yes, definitely focus on your weakest area first, especially with 40 days to study. If this is writing, than focus on writing. I strongly suggest going through the ‘Bonus Writing Section’ first. There you will go back to some basics, review and build. Then, go to the Writing Section of the course. As soon as you begin practicing your Task 1 and 2, submit your work our editors for correction, scoring and comments. This is an extra payment (6 cents per word) but it is very much worth it. Good studies!!!
