MGP practice questions - frequently asked questions

Plain answers about how MGP Exam Prep works: the exam, the questions, pricing, the free trial, and what you actually get.

No - and you should be wary of any site claiming otherwise. Every question here is original, written to mirror the style, difficulty, and judgment the real MGP exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The MGP exam spans 117 domains: Normal Structure and Function (7% of the exam); Molecular Genetic Principles (7% of the exam); Techniques and Methods (5% of the exam); Assay Performance and Validation (7% of the exam); Quality (6% of the exam); Ethical, Legal, and Regulatory issues (5% of the exam); Indications for testing (4% of the exam); Inherited Diseases (10% of the exam); Inherited cancer Syndromes (5% of the exam); Solid Tumors (11% of the exam); Hematopathology (9% of the exam); Pharmacogenetics (5% of the exam); Infectious Disease (6% of the exam); Identity Testing (4% of the exam); Histocompatibility (2% of the exam); Informatics (4% of the exam); Management and Informatics-General (3% of the exam). Every practice question on this site is tagged to one of these domains.

The domains are not weighted equally on the exam. By share of the marks: Solid Tumors 11%; Inherited Diseases 10%; Hematopathology 9%; Normal Structure and Function 7%; Molecular Genetic Principles 7%; Assay Performance and Validation 7%; Quality 6%; Infectious Disease 6%; Techniques and Methods 5%; Ethical, Legal, and Regulatory issues 5%; Inherited cancer Syndromes 5%; Pharmacogenetics 5%; Indications for testing 4%; Identity Testing 4%; Informatics 4%; Management and Informatics-General 3%; Histocompatibility 2%.
