This is Dr. Romano's response since he is the author the the Destroyer...Nancy
'There are 700 questions in the Bio questions in the DESTROYER. I have personally written each one. I have preached the idea of CONCEPTS for over 30 years to my students. In many many DESTROYER problems, I write the question to test more than one area. Often I amalgamate Biochemistry with Pathology.....sometimes Botany with Organic Chemistry.....Virology with BioChemistry, Anatomy with Physiology, and Histology with Pathology. Becoming a successful dentist or medical doctor often requires one to amalgamate concepts from different disciplines and APPLY them. I have always felt that just memorizing a question is often the wrong road to take. Concepts and understanding basic principles will always win out. Hope this helps."
