Sit a practice exam for the subject, read the report to see which MOS Schedule 3 units you missed, study those units, then retest. Repeat until you are consistently above the pass mark.
Each subject has its own page with the syllabus topics: see all CPL subjects, or read what to do after a fail and how to read your KDR.
