Is this aligned with the current CSEP exam?
Yes. Every question is written against the INCOSE Systems Engineering Handbook Fifth Edition (SEH v5.0). As of March 15, 2025, the CSEP and ASEP knowledge exams draw exclusively from v5.0 content, and this question bank was built for v5.0 from day one rather than patched up from the old v4.0 edition.
How long do I have access after purchase?
3 months from the date of purchase. That's well beyond the 6–8 weeks most candidates need to prepare. Your progress data — scores, attempt history, bookmarks — is kept indefinitely, so if you repurchase later your history is right where you left it.
What's the money-back guarantee?
If you're not satisfied within 30 days of purchase, contact us for a full refund, no questions asked.
Can I study on my phone/tablet?
Yes. The whole site is mobile-friendly — chapter drills, timed mock exams, and your progress dashboard all work on phones and tablets as well as on desktop. Because your scores, attempt history, and bookmarks are tied to your account rather than a device, you can practice on the go and continue seamlessly anywhere you sign in.
How is chapter practice different from a mock exam?
Chapter practice lets you drill a single topic, such as Risk Management, Architecture Definition, or Verification, with immediate feedback after every answer. Mock exams simulate the real test: 120 questions across all chapters in proportion to the real exam's emphasis, timed at one minute per question (120 minutes total), with no feedback until the end. Use chapter practice to build knowledge and mock exams to confirm you're ready.
Is this for CSEP only, or does it cover ASEP too?
Both. The CSEP and ASEP knowledge exams draw from the same handbook and use the same question format. The difference between the two certifications is your years of documented SE experience, not the exam content. This product is the right preparation for either credential.
I already studied for v4.0. Does that matter?
The core systems engineering processes haven't changed dramatically, but v5.0 introduced updated terminology, restructured process descriptions, and new alignment with ISO/IEC/IEEE 15288:2023. If your v4.0 knowledge is recent and solid, a focused review of the changes is enough. The chapter-targeted practice mode lets you drill the specific areas that shifted.
How hard is the CSEP & ASEP knowledge exam?
The knowledge exam is 120 multiple-choice questions — 100 scored plus up to 20 unscored beta questions — with 120 minutes total. Each question has a single correct answer. What makes it demanding is the breadth: all 31 sections of the SEH v5.0 are in scope, and the exam tests understanding, not just recall. Chapter-targeted practice lets you identify which sections need work and close those gaps before exam day rather than discovering them mid-exam.
How long should I study for the CSEP or ASEP exam?
It varies significantly by background. Candidates already practicing systems engineering day-to-day typically need less preparation than those coming from adjacent disciplines such as software or hardware engineering. Rather than following a fixed schedule, use the progress dashboard's exam readiness score and section mastery heatmap to see where you actually stand. When your weakest sections are consistently above 70% and your mock exam scores are stable, you're ready.
What's the difference between CSEP and ASEP?
The knowledge exam is identical for both certifications — same question bank, same handbook, same format. The difference is work experience. ASEP has no experience requirement; you qualify based on the exam alone. CSEP requires at least five years of documented systems engineering experience (for applicants with a qualifying degree). This product is the right preparation for either credential.
