I started my preparation at the beginning of April.
Since I am working full time I could study only during weekends (let's say 3 out of 4 a month) and I have dedicated to the preparation of the exam a total amount of around 60 hours.
As a study support I bought the 2019 GMAT official bundle (3 books package).
I started studying on
the Official guide. For each section I read first the theory part and then I did the exercises part. I used to do sessions of around 2 hours, the first hour dedicated to try to answer 30 questions, the second hour to read the explanations of the answers for the questions I did wrong but also for the correct ones. I followed the structrure of the books, so first the 2 Quantitative sections, then the three Verbal ones.
Then I switched to the Quantitative and Verbal review books. I adopted the same study method, but this time I alternated the quantitative and verbal sections, adopting the following pattern (with the introduction of the IR section questions online from
the Official guide): PS - RC - DS - CR - IR - SC
After finishing the exercises on those two books, I switched back to
the official guide and tried to write 4-5 different AWA essays.
Finally, after registering to the exam session, I got access to the two official practice exams and to the additional 90 practice questions.
I started doing the Practice Exam 1, adopting the #1 order. I got an overall score of 730 (Q49, V40, IR8). However, I quickly realized that it was not the best sequence for me, since I left as the last section, when I was more tired, the Verbal part, the one I am better at.
Then, I did the practice questions, in three different practice sections: first the 30 Q questions, then 30 V questions, in the third the remaining 15 V questions plus the 15 IR ones.
In the end last weekend I did the 2nd practice exam, adopting this time order #2, the same I then used yesterday. I got a much better result, as expected: 770 (Q49, V47, IR8).
