If you are studying for the medical oncology boards, ASCO-SEP is probably the first resource anyone recommends. It is the ASCO Self-Evaluation Program, and for good reason it is treated as the standard. Here is my honest take as a practicing oncologist: every fellow should buy ASCO-SEP, and it should be the backbone of your content review. But it is not enough on its own, and in 2026 it leaves real gaps that a modern learning platform fills.
TL;DR
ASCO-SEP is the authoritative content backbone for medical oncology board prep, and every fellow should buy it, especially if a program covers it.
It includes around 1,500 board style questions with short rationales, organized by disease site, and is updated on a regular cycle.
The 2026 weaknesses: a clunky interface, short explanations, a finite question bank, and no notebook, flashcards, or way to upload your ITE.
It covers medical oncology only. For hematology, pair it with ASH-SAP.
Use ASCO-SEP for breadth, then supplement with a modern platform that adds detailed compare and contrast explanations, spaced repetition, and adaptive practice.
What is ASCO-SEP?
ASCO-SEP is a digital self evaluation program from the American Society of Clinical Oncology sold as a 12 month subscription, with chapters organized by disease site and a bank of around 1,500 board style questions with rationales. The content is written and peer reviewed by oncology experts and updated on a regular cycle. Many fellowship programs buy it for their fellows, so check before you pay yourself.
One important boundary: ASCO-SEP is medical oncology, and it does not cover hematology in depth, so if hematology is a weak area, pair it with ASH-SAP. For a wider view of how the major options stack up, see our hematology-oncology question bank comparison.
What does ASCO-SEP do well?
ASCO-SEP does content better than almost anything else: authoritative chapters organized by disease site, writing that reflects current standards of care, and the weight of the society that shapes the field. The questions are written in the ABIM vignette style, so working through them is a fair preview of the exam. As a single, trustworthy pass through medical oncology it belongs at the center of your study plan, which is why it pairs well with a structured approach like our 2026 oncology board review strategy.
Where does ASCO-SEP fall short?
ASCO-SEP falls short on the modern learning experience: the interface is clunky, the question bank is finite at around 1,500 questions, and the explanations are short. It feels like a digital textbook rather than a study platform, and once you work through the bank you have largely seen it.
The short explanations are the gap I care about most as an educator. When you miss a question, a brief rationale tells you the right answer but does not teach you why the other options are wrong. Durable learning comes from comparing and contrasting every choice: why this one is correct, why that one is a trap, and what would have to change for a different answer to be right.
It is also missing the tools modern learners rely on. There is no notebook to organize what you are learning, no flashcard system with spaced repetition to lock in facts over time, and no way to upload your ITE so your studying targets your actual weak areas, the way our 6 month ABIM study plan recommends. There is no AI and nothing adaptive, so the program treats every learner the same.
ASCO-SEP vs a modern learning platform
The difference between ASCO-SEP and a modern platform is active learning. ASCO-SEP gives you authoritative content and a finite question bank with short explanations; a modern heme/onc platform adds the layer ASCO-SEP does not have.
On explanations, MeDucation goes long and detailed on purpose. Every question walks through why the correct answer is correct and why each wrong answer is wrong, the way a senior fellow would teach it at the whiteboard. That compare and contrast is where the learning actually happens, and it is the opposite of a one line rationale.
On tools, MeDucation includes a notebook to organize your learning, a flashcard app with spaced repetition so what you study comes back at the right interval, and the ability to upload your ITE so the platform targets your weakest areas instead of leaving you to guess. It is built specifically for hematology-oncology, with AI explanations and adaptive practice that a static program cannot offer. To be fair, ASCO-SEP wins on breadth and on its established, society backed content, and MeDucation as a newer platform does not replace it as your content reference. The two do different jobs. Disclosure: I founded MeDucation.
Is ASCO-SEP worth it in 2026?
Yes, ASCO-SEP is worth it in 2026, and you should buy it as the backbone of your board review, especially if your program covers it. Just do not stop there. On its own it is a finite question bank with short explanations and none of the tools that make studying stick. Build your foundation on ASCO-SEP, supplement with a modern platform for detailed explanations, spaced repetition, and ITE driven targeting, and add ASH-SAP if hematology is a gap. Our guide to passing the ABIM medical oncology boards and our complete guide to heme/onc board prep tie these pieces together.
Frequently asked questions
Is ASCO-SEP enough on its own to pass the boards?
ASCO-SEP is a strong foundation but most high scorers supplement it. With around 1,500 questions and brief explanations it covers content well, but it does not give you the volume of practice or the depth of explanation that builds durable recall, so pairing it with adaptive question practice tends to move scores more.
How many questions does ASCO-SEP have?
ASCO-SEP has around 1,500 board style questions with rationales, organized alongside chapters by disease site. Once you work through the bank you have largely seen it, which is why many fellows add a second source of questions for more practice volume before the exam.
Does ASCO-SEP cover hematology?
No, not in depth. ASCO-SEP is built for medical oncology, so benign and malignant hematology are not its focus. For hematology board prep, use ASH-SAP from the American Society of Hematology as the counterpart, and pair the two if hematology is a weak area.
How much does ASCO-SEP cost?
An individual ASCO-SEP subscription runs a few hundred dollars for 12 months, and the exact price depends on ASCO membership status and subscription length, with current figures on ASCO's site. Many fellowship programs provide it for free, so check with your program before you pay out of pocket.
What does ASCO-SEP not include that newer platforms do?
ASCO-SEP does not include a notebook, a flashcard app with spaced repetition, the ability to upload your ITE to target weak areas, AI generated explanations, or adaptive practice. These are the gaps worth supplementing with a modern heme/onc learning platform.
When should I start using ASCO-SEP?
Start reading ASCO-SEP chapters throughout fellowship as you rotate through each disease site, then lean on it heavily in your final board prep year. Early, consistent exposure beats cramming, and it lets the question bank reinforce content you have already seen on service.
