Suggestions to improve my quant score from 165 to 170

Hi,
I followed the I’m overwhelmed plan for quant and 1 month plan for verbal. I took the google form quizzes for foundation for quant and these are my scores:

Arithmetic: 42/50

Algebra: 35/36

Coordinate geometry: 38/38

Geometry: 42/44

Data Analysis Part 1: 27/30

Data Analysis Part 2: 31/44

Data Analysis Part 3: 15/15

In arithmetic, I made mistakes mostly because of not reading the question thoroughly or because I calculated wrong. I took timed hard quant quizzes and I got 80% in them. My conclusion is that my foundation isn’t bad but I’m struggling to manage time. I follow your time management strategy but still sometimes don’t have enough time to check and even if I do have time, I don’t know how to check properly. I saw that Greg suggests redundancy as a way to perfect score but I’m not sure I review my quant properly. How do I review my answers efficiently? Can you give me any other suggestions on how to optimize my score? I have my exam in a week.

I took the practice test 1 in ETS book and scored 167/170 in verbal and 165/170 in quant. In the first section, I didn’t have enough time to review my answers for quant but did better in the second section.

The one from the official guide?
