GMAT Strategy

Hi, folks

After one year of hard struggling with GMAT, a long way from 500 to 700+ questions, I got new problem I can't manage my performance in time in difficult questions.

Having surfed the Internet, I found two incredible articles - Magoosh's lecture and Manhattan's article.

The first lecture gave me the following plan below, which I started to use:
Q 75 0
65 5
55 10
45 15
35 20
25 25
15 30
5 35
0 37

V 75 0
66 5
57 10
48 15
39 20
30 25
21 30
12 35
3 40
0 41

The Stacey's article (https://www.manhattangmat.com/articles/keeping-pace.cfm)gave an idea of how I should control myself.

At the end I was able to do better SC (less than 1 min.) and CR (less than 1:30 min.). However, I still struggle with timing in quant and can't endure the even timing around the whole test.

I believe that many other people got success in time management. So, I created this post for any recommendations which might be useful in order to solve the problem.

I enclosed graphs and excel file with my timing for the last two test to the post.
The graphs shows that I was run out time. Thus, I missed 5 questions in Quant and 4 in verbal.

If somebody suggested new ideas how to improve, I would appreciate it.

Thanks in advance.
