About this exam

The Arab Board Oncology Part 1 is the basic-sciences component of specialty training in oncology within the Arab Board system. It is intended for physicians who are preparing to enter or progress through oncology training and who need to demonstrate a secure foundation in the science that underpins daily cancer practice. The examination samples cancer biology and molecular genetics, tumour immunology and immunotherapy principles, systemic therapy pharmacology, radiobiology and radiation physics, pathology and molecular diagnostics, imaging and staging, biostatistics and critical appraisal, epidemiology and prevention, supportive and emergency care, and professional conduct. Preparation should be active rather than purely reading-based: build a timeline around the domains, use primary textbooks and current guidelines for concepts, then test recall and reasoning with single-best-answer questions written in clinical vignettes. Keep an error log, revisit weak domains at spaced intervals, and practise justifying why the best answer is best and why the distractors fail. The Board publishes the current blueprint, format, timing, fees and pass standard on its official website; candidates should consult that source rather than rely on second-hand summaries.

What you'll study

Common questions

About Arab Board Oncology Part 1 preparation

What is the format of the Arab Board Oncology Part 1?

It is a written single-best-answer multiple-choice examination, delivered on paper or by computer depending on the sitting. Each item has one best option among the choices. Read the current candidate instructions issued by the Board for the definitive format, item style and examination regulations for your sitting.

How many questions are on the paper and how long does it last?

The Board publishes the current question count and time allowance for each sitting on its official website. Those figures can change, so this page does not quote them. Check your admission documents and the Board's candidate guidance before you plan your pacing strategy.

How difficult is the examination?

The challenge is breadth and integration rather than obscure trivia. Items often place a basic-science concept inside a clinical vignette, so you must recognise the principle, eliminate plausible distractors and choose the most defensible single answer. Candidates who only memorise lists without mechanisms usually find it harder than necessary.

What score do I need to pass, and can I retake it?

The pass standard and retake rules are set by the Board and published in its current regulations. They are not fixed forever, so confirm the current pass score, number of permitted attempts and any waiting period directly with the Board rather than relying on what previous candidates report.

In what order should I study the domains?

Start with cancer biology, molecular genetics and pharmacology, because these concepts recur across pathology, imaging and systemic therapy questions. Then add immunology, radiobiology and physics, followed by pathology and diagnostics. Finish with biostatistics, epidemiology, supportive care and ethics, while continuing spaced review of earlier domains.

What are the most common failure modes?

Common patterns are studying only clinical guidelines, skipping physics and biostatistics, memorising drug lists without mechanisms, and doing questions before building a knowledge base. Others are failing to review wrong answers, over-studying favourite topics, and not practising single-best-answer reasoning under time pressure.

Are current treatment guidelines enough for Part 1?

No. Guidelines are useful for clinical context, but Part 1 tests the scientific foundations behind them. You need mechanism-level understanding of carcinogenesis, drug action and resistance, radiation biology, tumour pathology and study design. Use guidelines to anchor concepts, not as a substitute for basic-science textbooks and structured revision.

How should I use practice questions?

Use them as a diagnostic and learning tool, not a scoreboard. Answer without looking up, then write a one-line reason for the correct option and for why each distractor fails. Group errors by domain, return to the underlying text, and retest the same concept later at spaced intervals.

How far in advance should I start preparing?

Build a realistic plan based on your gaps, not a fixed number of weeks. Map the domains, estimate your weakest areas, and schedule repeated review cycles rather than one long pass. Regular short sessions with active recall and question review are more effective than last-minute reading, especially for pharmacology, physics and biostatistics.
