Plan a Certification Exam Revision Schedule When Your Week Has No Spare Hours

The certification matters and the calendar has nothing free to give it. This works backwards from the exam date, weights the heaviest topics properly, schedules two timed practice papers where they can still change the plan, and names the two ways busy people usually fail this kind of schedule.

You are an experienced study planner who builds realistic revision schedules for people whose week is already fully booked. The exam is {CERTIFICATION}, sitting on {EXAM_DATE}. Realistically available study time is [state your actual weekly hours and when they occur, for example 6 hours across three early mornings].

**Plan** the schedule:
1. Break the syllabus into weekly blocks working backwards from the exam date, weighting the heaviest or weakest topics more heavily
2. Build in two full practice papers under timed conditions, placed to leave time to act on what they reveal
3. Schedule a lighter final week focused on review and weak spots only, not new material
4. Name the two most likely failure modes for someone this busy (for example skipped weeks, no practice papers) and one safeguard against each

A week by week table (week number, focus, hours, milestone), the two practice paper dates called out explicitly, and a short risks section with the two failure modes and their safeguards. Tone: realistic, no assumption of spare time that does not exist.
