First off — congrats on taking your first attempt! A **595 baseline** with mocks in the **625–645** range means you’re already in striking distance of 675+, and the jump is absolutely doable in one month with a sharp, strategy-driven approach. Let’s break this down by your points and work toward a **re-attack plan**:
---
### 1. **Score Dip vs. Mocks**
* The gap between mocks and official GMAT scores is often caused by:
* **Early misses** (especially in GMAT Focus where adaptive scoring is more sensitive upfront).
* **Time management breakdown** — rushing sections to “save” time hurts accuracy in mid/late sets.
* **Different question flavor** — official questions often have subtler traps than prep ones.
👉 My read: You may have been “mock-trained” for patterns but the **official exam punished the first 2–3 misses** harder than your mocks did.
---
### 2. **Section Order (V > DI > Q)**
* Smart to put Quant last if that’s your strong suit.
* The **risk**: fatigue can creep into DI, which is already mentally taxing.
👉 If you found yourself drained during DI, test a switch: **V > Q > DI** in a couple of mocks. Sometimes doing Quant second preserves mental freshness for the heaviest “processing” section.

### 3. **DI Pain Points**
You’re spot on that **official DI feels way tougher** — especially DS, TPA, and GI TA.
Some strategies:
* **DS (Data Sufficiency)**:
* Always rephrase the question to what is *truly* being asked.
* Avoid “quick satisfactions” — many traps hinge on mixing up sufficiency vs. actual solution.
* Train on **OG Advanced** and GMAT Club DS 700+ tagged sets.
* **TPA (Table/Process Analysis)**:
* Spend the first 20–30 seconds just mapping what the table is telling you.
* Pre-label columns and relationships — rushing here is what leads to time drains later.
* **GI/TA (Graphs & Interpretation)**:
* Practice *estimation* and *pattern spotting*. You don’t always need full calculations.
* Practice under strict **2-min per Q discipline** — official DI is designed to punish over-investing in one question.
👉 **Time Strategy for DI:**
* 20–21 Qs → ~40 min → avg. **~2 min/Q**.
* My recommended split:
* **Quick scan (10–15 sec)** before diving.
* Bail-out threshold: If you’ve spent **>2.5 min** and haven’t framed the approach, guess smart and move.
* Protect your pacing in the **first 5 DI Qs** — adaptive algorithm is sensitive here too.

### 4. **Prep Resources**
* **
e-GMAT & CrackVerbal** → solid for Verbal frameworks.
* **
TTP (
Target Test Prep) for DI** → yes, worth it if you’re struggling.
TTP’s DI bank is more aligned to “official-style toughness” than many others.
* **Must-do**: Official Guide + Advanced OG for DI + GMAT Focus Official Practice Exams. That’s the closest to test-day feel.

### 5. **One-Month Re-Attempt Strategy**
**Week 1–2:**
* Diagnose weak DI subtypes (log every error by *type* not just score).
* Drill DS/TPA sets daily (10–15 Qs).
* Run sectional mocks: 30 min DI, 45 min Verbal, etc.
**Week 3:**
* Full-length mocks (2–3 official + 1 third-party).
* Experiment with section order (V>Q>DI vs. V>DI>Q).
* Focus on stamina: simulate test-day environment, exact breaks, etc.
**Week 4:**
* Sharpen timing discipline.
* Light review of Quant & Verbal traps (don’t over-invest in Q).
* At least **1 rest day before test**.

### 6. **Your 675 Goal**
* You’re 80 points away.
* Realistically, that’s **5–7 fewer misses overall** (especially in DI + first 5 Qs per section).
* With Quant strong, the jump will largely come from:
* Keeping DI under control.
* Avoiding careless misses in Verbal.
* Maintaining mental energy till the end.
