Training course
This is a free, self-paced reading course for the CAPM: Certified Associate in Project Management: PMI’s entry-level credential, aimed at people already contributing to project teams, moving into project roles, or building toward the PMP. It is written to be read straight through, in order, before you start drilling practice questions. CAPM rewards vocabulary and judgment more than experience, so the first job is to get the language right: what a product backlog actually is, how a sponsor differs from a PMO, when float matters, and why a requirement needs to be traced.
The course is organized as one module per exam domain, in the order PMI publishes them in the Examination Content Outline, and each module carries the domain’s published weight. That matters more on CAPM than on most exams because the weights are lopsided. Fundamentals and business analysis together carry 63% of the exam, and 63% of this course, while the predictive, plan-based domain is the smallest at 17% despite being the one candidates instinctively over-study. Reading in weighted order keeps you from spending three weeks on earned value math and a weekend on requirements elicitation.
What the course covers
Project Management Fundamentals and Core Concepts
Module 1 · 36%The heaviest domain by a wide margin. Life cycles, predictive, iterative, incremental, adaptive, and hybrid; the distinction between project, program, and portfolio; the components of a project management plan; roles and responsibilities across sponsor, project manager, team, stakeholders, and PMO; and the common problem-solving tools CAPM expects you to name on sight, root-cause analysis, fishbone diagrams, 5 Whys, and decision trees.
Predictive, Plan-Based Methodologies
Module 2 · 17%The lightest domain, and the most technical. When a predictive approach is the right call; schedule components, work breakdown structure, activity list, network diagram, critical path, and milestones; and project controls through earned value, variance analysis, and change control. Forward and backward passes, float and slack, and the earned value family (CV, SV, CPI, SPI, EAC, ETC, VAC, and TCPI) appear as calculation items, so this module is worked rather than read.
Agile Frameworks and Methodologies
Module 3 · 20%When an adaptive approach fits; planning iterations, sprints, and releases; the documentation adaptive projects run on, information radiators, burn charts, and kanban boards; the components of an adaptive plan, from product roadmap through product backlog, sprint backlog, and increment; and task management practices such as story mapping, story-point estimation, and WIP limits. Scrum vocabulary is essential, but PMI’s framing is deliberately framework-neutral and tests why an approach fits at least as often as how its ceremonies work.
Business Analysis Frameworks
Module 4 · 27%The second-heaviest domain, and the one that catches candidates who studied an older CAPM syllabus. Business analyst roles versus project manager roles; stakeholder communication through the stakeholder register, engagement matrix, and communication planning; requirements elicitation by interview, workshop, prototype, and observation; product roadmap types; how the chosen methodology shapes the business analysis approach; and validating requirements through delivery with traceability, acceptance criteria, and the difference between verification and validation.
How to use it
Read a module, then take the matching portion of the CAPM practice exam rather than saving all the questions until the end. CAPM is a recognition exam. The wrong answers are usually real terms used in the wrong place, so testing a domain immediately after reading it is the fastest way to find out whether you know a definition or merely recognize the word. If you want to see the question style before committing, the free CAPM sample is a short set drawn from the same bank. Module 2 is the exception to read-then-test: work the earned value and critical path arithmetic on paper until the formulas come back without prompting. The course modules themselves open once you are signed in to a free Certifym account.
For exam logistics, question count, timing, the eligibility requirement of a secondary degree plus 23 contact hours of project management education, pricing, and how Certifym’s 65% practice threshold relates to PMI’s undisclosed pass mark, see the CAPM certification guide.
Critical path, forward and backward passes, and float
This is the most mechanical lesson on the exam and one of the most reliably examined. Work it with a pen and paper. The technique never changes: build the network, run a forward pass, run a backward pass, and read off the float.
What the critical path is
The critical path is the longest path through the network, and it determines the shortest time in which the project can finish. That sounds contradictory until you see why: every path must complete, so the project cannot finish before the longest one does.
Activities on the critical path have zero total float — no room to slip. Delay any of them by a day and the project finishes a day late, unless you take corrective action. A network can have more than one critical path, and having several increases risk because there are more ways to slip.
Finding the path by enumeration
For small networks, list every path and add the durations. Consider a project with these activities:
- A, 3 days, no predecessor
- B, 5 days, after A
- C, 2 days, after A
- D, 4 days, after B
- E, 6 days, after C
- F, 2 days, after D and E
The paths are A-B-D-F = 3 + 5 + 4 + 2 = 14 days, and A-C-E-F = 3 + 2 + 6 + 2 = 13 days. The critical path is A-B-D-F at 14 days, and the project duration is 14 days. Path A-C-E-F has one day of float across it, and it is a near-critical path — one day of slippage anywhere on it makes it critical too.
The forward pass
The forward pass calculates early start (ES) and early finish (EF) for every activity, moving left to right. This lesson uses the convention that the project starts at time zero and EF = ES + duration. Some materials start at day 1 and use EF = ES + duration - 1; both give the same float values, so read each question's convention and stay consistent within it.
Rules: the first activity has ES = 0. For any other activity, ES = the largest EF among its predecessors, and EF = ES + duration. Taking the largest matters — an activity with several predecessors waits for the slowest.
Applying this to the network above:
- A: ES 0, EF 3
- B: ES 3, EF 8. C: ES 3, EF 5
- D: ES 8, EF 12. E: ES 5, EF 11
- F: predecessors D (EF 12) and E (EF 11), so ES 12, EF 14
The project duration is 14 days, matching the enumeration.
The backward pass
The backward pass calculates late finish (LF) and late start (LS), moving right to left from the project end. Rules: the last activity's LF equals the project duration. For any other activity, LF = the smallest LS among its successors, and LS = LF - duration. Taking the smallest matters — you must finish in time for the earliest successor that needs you.
- F: LF 14, LS 12
- D: successor F has LS 12, so LF 12, LS 8. E: LF 12, LS 6
- B: successor D has LS 8, so LF 8, LS 3. C: successor E has LS 6, so LF 6, LS 4
- A: successors B (LS 3) and C (LS 4); take the smaller, so LF 3, LS 0
Total float
Total float is how long an activity can be delayed from its early start without delaying the project finish. Calculate it either way — they agree:
Total float = LS - ES = LF - EF
- A: 0 - 0 = 0. B: 3 - 3 = 0. D: 8 - 8 = 0. F: 12 - 12 = 0.
- C: 4 - 3 = 1. E: 6 - 5 = 1.
Zero-float activities A, B, D, and F form the critical path, which confirms the enumeration. C and E each have one day of total float — but note that this float is shared along the path. If C uses its day, E has none left.
Free float
Free float is how long an activity can be delayed without delaying the early start of any immediate successor. Calculate it as:
Free float = (earliest ES among successors) - EF of this activity
For C: successor E has ES 5; C's EF is 5; free float = 0. For E: successor F has ES 12; E's EF is 11; free float = 1. So E can slip one day without affecting anything else, while C cannot slip at all without pushing E.
Total float belongs to the path; free float belongs to the activity. When a question asks how long an activity can be delayed "without affecting the project completion date," it wants total float. When it asks "without affecting any successor" or "without affecting the next activity," it wants free float.
Negative float
If an imposed end date is earlier than the calculated finish, the backward pass starts from that imposed date and produces negative float. Negative float of minus three days means the schedule is three days short of what the constraint demands — you are already behind before starting. The response is compression, scope reduction, or renegotiating the date, and identifying which activities carry the negative float tells you where to act.
Exam habits
Draw the network rather than reasoning from the table. Enumerate paths for small problems as a cross-check on your passes. Read carefully whether the question wants total or free float, whether it asks for duration or a date, and which day-numbering convention it uses. And remember the definition that resolves most conceptual items: the critical path is the longest path and produces the shortest possible duration — it is not the path with the most important activities.
Frequently asked questions about the CAPM training course
Is the CAPM training course free?
Yes. The course costs nothing to read and opens once you are signed in to a free Certifym account, no payment and no card.
How is the course structured?
One module per domain of PMI’s CAPM Examination Content Outline, in PMI’s published order, with each module weighted to the domain’s published percentage: 36%, 17%, 20%, and 27%. Within each module the material is broken into short lessons, followed by key terms and further reading.
Do the 23 contact hours count from this course?
No. PMI requires 23 contact hours of project management education from a qualifying provider, and Certifym is not one. PMI’s own free Project Management Basics course satisfies the requirement and maps to the exam outline; use this course as a study companion alongside it, not instead of it.
What do I need to know before starting?
Nothing specific about project management. CAPM is designed for people entering the field, and the course starts from the vocabulary. What helps is having been on a project of some kind, the roles, handoffs, and change requests land faster if you have watched them happen.
What should I do after finishing the course?
Move to the CAPM practice exam and work until you are clearing the threshold across all four domains rather than carrying a weak business analysis score on the strength of module 1. Then confirm your 23 contact hours are documented and book with Pearson VUE.
Is the course current with the CAPM exam outline?
The course is built against the CAPM outline effective July 2023, which replaced the earlier process-group structure with the four domains above and made agile and business analysis first-class exam content. PMI can revise the outline at any time; verify the current Examination Content Outline on the PMI website before you sit the exam.
