+# Subordinate Clauses: 10/10 — Word Order Is Solid
+
+Scored a perfect 10/10 on the lesson 4 drill covering *weil/dass/ob/wenn* verb-final order, multi-verb endings
+(modal + infinitive, Perfekt with separable verbs), and the *ob* vs. *obwohl* meaning distinction. Accusative
+endings were woven into every question as a background check and didn't trip up the result.
+
+This was the top-priority gap identified in the diagnostic session (0003), and it's the first lesson topic to
+score perfectly on the first attempt — a strong signal the format (single grammar concept + multi-verb edge
+cases + a dedicated meaning-distinction box) works well for this user.
+
+**Implications:** Move to the next diagnostic priorities. Perfekt/Partizip II formation for separable verbs
+deserves its own dedicated lesson — it was only touched briefly here via *abgesagt*. Accusative adjective
+endings could graduate from "woven in as a check" to a focused drill of their own. Noun gender under pressure
+(memorize-only nouns like *Kostenvoranschlag*, *E-Mail*) is still untouched since lesson 2 and scored low
+there (4/10) — worth revisiting before it's forgotten further.
