### The Emotional Struggle
I hit a plateau at 665 for 4 weeks straight. I was studying 4 hours every night after 12-hour consulting workdays. My brain was completely fried, and my mock scores actually began dropping due to memory fatigue. I had to force myself to take a complete 4-day rest freeze.

### The Turning Point
Realizing that GMAT Data Sufficiency is not a math test, but a logic test. I stopped trying to solve every algebraic expression to the final number and began analyzing statement boundaries. This single shift saved me 15 minutes per section.

### Study Schedule & Logistics
1.5 hours before work (07:00 - 08:30) focusing on high-difficulty CR, and 1 mock exam every Saturday morning.

### Final Advice
*"Protect your sleep and your cognitive recovery. GMAT Focus measures processing speed; a tired brain cannot perform at a Q85 level. Treat study rest days as a critical part of your curriculum."*
