Pharmacology MCQs

I am Dr Ray Makar, retired dermatologist and USMLE teacher. I am devoting my time and effort to help medical students and foreign doctors to pass USMLE with high scores and on the first attempts.

I wrote a lot of books, platforms and online pages containing the most repeated and remembered USMLE questions that helped a lot of students reach their goals for a good future in the USA.

About Medical Student

On this website, I am focusing on medical students, during college and after graduation up the boards. I will post a lot of short and long questions on all branches of basic and clinical medicine to help you understand concepts of medicine.

Questions, answers and explanations are better tools to remember concepts than reading textbooks and study notes. While they do not replace study books, QA is a valuable tool in review and collecting knowledge.

Please let me know if you have any questions or if you need any help PM me on my Facebook Page. I will be more than happy to help you.

Thank you and have the best of luck

Ray
