7 Week Study Plan - suggestions, comments, ideas, etc please

Hi,

I'm a non-native speaker with an undergraduate degree in Economics. The last time I studied English was 6 years ago when I took the FCE exam.

Before starting, I took a GMATprep v.1 - 1 exam an the result was 680 (Q49 ; V33).

Resource List:

- MGMAT 8 Strategy Guides;
- OG 12
- Quant Review 2nd Edition;
- Verbal Review 2nd Edition;
- Kaplan Verbal Workbook;
- GMATclub free tests.

My current schedule for the 7 weeks is:

Week 1 - MGMAT SC Strategy Guide and OG 12 SC section; Veritas Free CAT

Week 2 and 3 - MGMAT Quantitative Strategy Guides and OG 12 Quantitative sections; MGMAT CAT 1 e 2

Week 4 - Kaplan Verbal Workbook; MGMAT CAT 3

Week 5 - MGMAT RC and CR Strategy Guides and OG 12 RC and CR sections MGMAT CAT 4

Week 6 - Quant Review 2nd Edition and Verbal Review 2nd Edition; GMATclub free tests; MGMAT CAT 5

Week 7 - MGMAT CAT 6 and GMATprep v.1 - 2; Redo all the questions that I got wrong or that took too long to solve from OG 12, Quant Review 2nd Edition and Verbal Review 2nd Edition.

I'm studying between 6 to 8 hours a day, 6 days a week and I'm currently finishing my third week.

The Veritas free CAT result was 630 (Q42; V37)
The MGMAT CAT 1 result was 680 (Q47; V36)

Any advice?

Thanks in advance.
