What makes PSM I difficult

You have 60 minutes for 80 questions, which is 45 seconds per question. The pass mark is 85%, so you can miss only 12 questions. Many questions test exact words from the Scrum Guide, such as who is accountable, who decides and what “must” happen. Answers that sound sensible in a real company are often wrong in Scrum.

A 14-day study plan

WhenWhat to do
Days 1–2Read the Scrum Guide 2020 twice. It is short. Read slowly the second time and note every “must”, “only” and time limit.
Days 3–6Work through the free PMCLEAR Scrum course, one or two lessons a day. Each lesson explains one part of the Scrum Guide with a case and questions.
Days 7–8Do the practical labs. You make Scrum Master decisions in real team situations and see the Scrum Guide logic behind each choice.
Days 9–11Answer practice questions by topic. Read every explanation, also for the questions you got right. Write down each rule you missed.
Days 12–13Take full timed tests: 80 questions in 60 minutes. Aim for 90% or more, so you have a safety margin above the 85% pass mark.
Day 14Read the Scrum Guide one last time, rest, and take the real assessment when you feel calm.

Go faster or slower: the order matters more than the number of days.

8 Scrum Guide rules people miss

  1. A Sprint is one month or less. A new Sprint starts right after the previous one ends.
  2. The Scrum Team is the Product Owner, the Scrum Master and the Developers. It is typically 10 or fewer people.
  3. The whole Scrum Team creates the Sprint Goal during Sprint Planning. The Developers decide how to do the work.
  4. Only the Product Owner can cancel a Sprint, and only when the Sprint Goal becomes obsolete.
  5. The Daily Scrum is a 15-minute event for the Developers. The Scrum Master makes sure it happens but does not run it.
  6. An Increment is born as soon as a Product Backlog item meets the Definition of Done. You can release it before the Sprint Review.
  7. Each artifact has a commitment: Product Backlog → Product Goal, Sprint Backlog → Sprint Goal, Increment → Definition of Done.
  8. Time limits for a one-month Sprint: Sprint Planning 8 hours, Sprint Review 4 hours, Sprint Retrospective 3 hours. Shorter Sprints usually have shorter events.

The 2017 vs 2020 trap

Many old practice tests still use words from the 2017 Scrum Guide. The PSM I assessment uses the 2020 version. If a question uses old words, think in the new rules.
