ExploreAbout this exam
The Iranian Comprehensive Basic Medical Sciences Examination (علوم پایه پزشکی) is the gate that medical students in Iran generally must clear after the basic-sciences phase of the curriculum, before entering the clinical years. It is a high-stakes, multiple-choice assessment that samples the full preclinical foundation - gross anatomy, histology and embryology, physiology, biochemistry and molecular biology, microbiology, immunology, pathology, pharmacology, medical genetics, biostatistics and epidemiology, medical ethics and health law, and nutrition with community medicine. Because the exam is cumulative, it rewards students who kept pace with coursework rather than those who cram in the final weeks. Effective preparation usually means working through each subject in blocks, then switching to mixed-topic practice so you can retrieve facts under time pressure and recognize the classic two-step stems the exam favors. Prioritize high-yield mechanisms and structures, keep a personal error log, and revisit weak areas on a spaced schedule. The page below answers the practical questions candidates ask most often.

What you'll study
About Iran Medical Basic Sciences Exam preparation
Who sits this exam, and what does passing it allow me to do?
It is aimed at medical students who have finished the preclinical/basic-sciences stage of the curriculum. Passing is normally the prerequisite for progressing into clinical training. Exact eligibility rules, including any rules for repeaters or graduates of foreign programs, are set by the administering body, so check its current announcement rather than relying on older student accounts.
What is the format of the exam?
It is delivered as multiple-choice questions across the basic medical sciences, with the subject areas weighted according to the official blueprint. Expect single-best-answer items, some of which require two or three reasoning steps rather than simple recall. The official body publishes the current structure and subject distribution; treat any figure you hear from peers as unverified.
How many questions are there, and how long do I have?
Those numbers change between administrations and are announced by the official administering organization. Do not plan your pacing around a remembered figure from a previous year. Before the exam, confirm the current question count and time limit from the official source, then practice with timed mixed sets that match that structure.
How hard is it, really?
It is a broad, cumulative exam, and the difficulty comes from breadth rather than trick questions. Most items test standard mechanisms, structures, and diagnostic patterns. Candidates who fail usually have one or two neglected subjects rather than a general knowledge gap, so an honest self-audit early on matters more than raw study hours.
Can I retake it, and how is the score used?
Retake rules, score reporting, and any validity period are set by the administering body and are not uniform across years. Check the current regulations directly. Practically, plan as though you have one serious attempt: build a schedule that covers every subject at least once, because a single weak domain can pull a total score below the threshold.
In what order should I study the subjects?
Start with the subjects that underpin others - physiology, biochemistry, and anatomy - then layer on pathology, pharmacology, and microbiology, which reuse that foundation. Genetics, immunology, and biostatistics are compact and reward early, regular review. Finish with mixed-topic practice and spaced review of your error log rather than starting new material late.
What are the most common failure modes?
Neglecting one low-weight subject entirely, memorizing lists without understanding mechanisms, and doing practice questions only after all content review is finished. Another frequent problem is skipping ethics, biostatistics, and community medicine because they feel peripheral; they are reliable, learnable points. Mixed practice from early on exposes these gaps while there is still time to fix them.
How do I handle questions I cannot answer?
Answer every item - there is no benefit to leaving blanks in a single-best-answer format. Eliminate options using mechanism-based reasoning, flag genuinely uncertain items, and move on rather than losing minutes. In practice sets, review every flagged question afterward and record why the correct option was right, not just what it was.
Where do I confirm fees, dates, and passing scores?
Only from the official administering organization's website and its current exam announcement. This page deliberately does not state fees, dates, passing thresholds, or score validity because those details change and must be verified. Register early, keep your documents ready, and re-read the announcement for any late changes to the format.
