MDT practice questions - frequently asked questions

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

The MDT exam spans 4 domains: General Laboratory (18% of the exam); General Molecular Diagnostics Theory (20% of the exam); Molecular Laboratory Procedures (10% of the exam); Diagnostic Methods (52% 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: Diagnostic Methods 52%; General Molecular Diagnostics Theory 20%; General Laboratory 18%; Molecular Laboratory Procedures 10%.

The MDT exam has 200 questions and is completed in 3 hours. Our timed practice mirrors that length and pacing, so exam day feels familiar.
