Per-category CBLE diagnostic: drill one exam category at a time
The general practice test mixes all six CBLE categories together. If the trainer or a mock exam result already told you which category is weak, drilling that category alone, with no other questions in the way, is the fastest way to fix it. Pick a category below. Each one is free, ungated, and scores you with the governing citation after every question.
28 questions 33 questions 23 questions 20 questions 7 questions 9 questions
Broker Compliance
19 CFR Part 111 broker licensing and conduct, bonds, recordkeeping, penalties, IPR, marking, and antidumping and countervailing duty administration: the second-largest category on the April 2026 exam.
Entry / Entry Summary
Entry filing deadlines, entry types, CBP forms, in-bond movement, foreign trade zones, and bonded warehouse rules: the single largest CBLE category on every recent paper.
Valuation and Duty Assessment
Transaction value, the six-method valuation hierarchy, assists and related-party pricing, liquidation deadlines, and duty relief for damaged or defective goods.
Classification
The General Rules of Interpretation in order, Section and Chapter Notes, and worked heading-level classification calls across real product families.
Modernized Drawback
19 CFR Part 190 drawback categories, the 8-digit substitution standard, claim deadlines, and the difference between direct identification and substitution drawback.
Practical Exercise
Applied, multi-step scenarios that combine classification navigation, valuation math, and recordkeeping lookups the way the real exam's practical-exercise category does.
