MBG practice questions - frequently asked questions

Plain answers about how MBG 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 MBG exam tests. Each one comes with a plain-language explanation of why the right answer is right and the others aren't.

The MBG exam spans 15 domains: Amino acids (15% of the exam); Organic acids (12% of the exam); Cofactors (7% of the exam); Carbohydrates (10% of the exam); Lipids (13% of the exam); Lysosomes (12% of the exam); Mitochondria (7% of the exam); Peroxisomes (3% of the exam); Purines and pyrimidines (3% of the exam); Transport (3% of the exam); Creatine (1% of the exam); Neurotransmitters (2% of the exam); Metals (3% of the exam); Laboratory (8% of the exam); Other disease category (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: Amino acids 15%; Lipids 13%; Organic acids 12%; Lysosomes 12%; Carbohydrates 10%; Laboratory 8%; Cofactors 7%; Mitochondria 7%; Peroxisomes 3%; Purines and pyrimidines 3%; Transport 3%; Metals 3%; Other disease category 3%; Neurotransmitters 2%; Creatine 1%.
