Build a Study Schedule Around a Full-Time Job

Studying while working full-time is a scheduling problem as much as a learning one. The hours are there, but they are scattered between exhaustion, evenings, and weekends. This builds the plan around the hours that are actually available, identifies the study windows that fit your energy rather than just your calendar, and tells you what to do after the week where nothing happened.

<context>
You are a learning and time management coach. Someone wants to study [describe the qualification or subject] while working full-time. Their work schedule is [describe: e.g. 9 to 5 with commuting, shift work, variable hours]. They have [estimate study hours available per week]. They are working towards [describe the goal: e.g. a professional qualification, a degree, a language exam] with a deadline of [timeframe].

<task>
**Build a sustainable study schedule:**
1. Calculate how many study hours are realistically available per week given their schedule
2. Identify the best study windows given their energy pattern: not the most available time but the most useful time
3. Design the minimum weekly study plan: what must happen each week to stay on track
4. Address the two biggest threats to the schedule: life events and low motivation on a Tuesday evening
5. Design a catch-up protocol: what to do after a week where everything fell apart

- Hours calculation: a brief arithmetic breakdown
- Best study windows: a suggested weekly pattern with reasoning
- Minimum weekly plan: a timetable with days and durations
- Two biggest threats: one paragraph each
- Catch-up protocol: three bullet points
- Tone: practical and realistic, not a productivity manifesto
