BB/TM practice questions - frequently asked questions

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

The BB/TM exam spans 15 domains: Clinical Practice (14% of the exam); Histocompatibility and Tissue Banking (1% of the exam); RBCs and RBC Components (10% of the exam); Apheresis (8% of the exam); Hazards of Transfusion: Specific Adverse Events (10% of the exam); Plasma Components and Derivatives (6% of the exam); Infectious Hazards of Transfusion (4% of the exam); Blood Donors and Blood Collection (7% of the exam); Management, Quality, Legal, & Regulatory Issues in Transfusion Med. & Transplantation (6% of the exam); Surgery Patients (7% of the exam); Biovigilance (1% of the exam); Platelet and Platelet Components (6% of the exam); Obstetric and Pediatric Patients (7% of the exam); Hematopoietic Progenitor Cell (HPC) Transplantation (11% of the exam); Management and Informatics-General (2% 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: Clinical Practice 14%; Hematopoietic Progenitor Cell (HPC) Transplantation 11%; RBCs and RBC Components 10%; Hazards of Transfusion: Specific Adverse Events 10%; Apheresis 8%; Blood Donors and Blood Collection 7%; Surgery Patients 7%; Obstetric and Pediatric Patients 7%; Plasma Components and Derivatives 6%; Management, Quality, Legal, & Regulatory Issues in Transfusion Med. & Transplantation 6%; Platelet and Platelet Components 6%; Infectious Hazards of Transfusion 4%; Management and Informatics-General 2%; Histocompatibility and Tissue Banking 1%; Biovigilance 1%.
