WDM11 Critical path analysis Topic Questions
Every WDM11 Critical path analysis topic question from the 2018–current syllabus, drawn from 16 papers (2019–2026) and grouped by syllabus point. Each row opens a page listing the exact question numbers, marks and a direct link into the paper. These are questions by topic, not full papers, so you can revise one topic at a time.
Core finding
4.4 Total float. Gantt (cascade) charts. Scheduling. is the most frequently assessed subtopic in Critical path analysis, with 43 topic questions and 114 marks across 15 papers. 4.3 Algorithm for finding the critical path. Earliest and… follows with 41 topic questions and 98 marks. The topic contains 4 subtopics, 98 topic questions and 272 marks in total. Rows count only the parts tagged to that subtopic, keep the same colour in both charts and repeat paper count, tagged marks and year range in the native table.
Topic question count and mark distribution
Subtopics are on the vertical axis and sorted from highest to lowest. Only the parts whose knowledge graph matches a subtopic are counted for it, and percentages are each row's share of the tagged total in that chart. A part tagged to several subtopics is counted in each bar, so the bars are not a partition of the topic total.

Topic question rules and edge cases
- How many subtopics does Critical path analysis contain?
- This page lists 4 subtopics tagged to the current syllabus. They are ordered by syllabus number, then alphabetically, and each row opens a page of matching past-paper questions.
- How are the subtopic question and mark totals calculated?
- A multiple-choice question contributes one item and its marks to every subtopic it is tagged with. A structured question contributes one item per tagged part, and that part’s marks; untagged parts of the same question are not counted here. A part tagged to several subtopics therefore appears under each of them.
- Why do some subtopics have no numbered prefix?
- Practical-skills statements and some syllabus bullets are unnumbered. Numbered statements come first; unnumbered statements and ties are sorted alphabetically.
- Is the LaTeX rendered without JavaScript?
- Yes. Subtopics that contain formulas are converted to static KaTeX HTML during the build, and the KaTeX stylesheet is served from the same site.
