Improve my score to 730 in 30 days

Happened to know Magoosh through one of the emails from UC Berkeley Haas, listed among recommended GMAT courses.
- GMAT score before: 690
- GMAT score after: 730
- Duration: 31 days
*Good
- Very structural approach on how I can customize my practice
- Good and detailed explanation to let me know how to avoid the same mistake
- Show recommended lesson at the bottom on answer: trust me, you will love this tool
- Wonderful customer service,: indeed i had 31 days away from my exam, but the CS officer was so kind to extend 1 day for free (from my purchase of 30-day package) so that i could review on my last day before exam.

*Bad
- They have multiple mobile apps like Flash card for Verbal, Maths... i hope they can integrate all into one app - one platform
