Field Guide · For medical students

A week plan that survives postings and duties.

Plan your study (medical students), part 2: a week plan around postings and a night duty, tested on free ChatGPT. It fits; the hours don't add up.

Postings till 2, a night duty on Wednesday, and Thursday morning gone to sleep. A week like that has 17 hours of study in it somewhere, and a plan that ignores the duty falls apart by Thursday. This is part 2 of the Field Guide series on planning your study as a medical student: one job, tested on a real screen, with the catch said plainly.

The job, and what to type

Part 1 made the month-by-month plan. This part makes the week you actually live. The week below is a sample, made up for this demo: posting hours, one night duty, four subject names and a 17-hour budget, nothing from inside a subject. Type your own timetable, subjects and hours in its place.

Make me a study plan for one normal week, around my postings and duties. I'm an MBBS student.
- Postings Monday to Saturday, 8 am to 2 pm.
- Night duty on Wednesday, 8 pm to 8 am. On Thursday I sleep until 1 pm.
- No study after 11 pm. Saturday evening from 6 pm is free, no study.
- I can study 17 hours in the week in total.
- My subjects, with how sure I feel about each (1 = weak, 3 = strong): Pathology 1, Pharmacology 1, Microbiology 2, Forensic Medicine 3. Give the weak subjects more time.
- No sitting longer than 3 hours.
- Show each day with the times, the subject and the hours, then the total hours for each subject.
- Plan at subject level only. No topic lists.
- If an extra duty comes up one week, tell me what to drop first.

Why these lines

The hours you can't study go in first: postings, the duty, the sleep after it, nothing after 11 pm, Saturday evening off. That stops it planning a week you don't have. Then the 17 hours you can study, and your subjects rated 1 to 3 for how sure you feel, so it knows where the extra time goes. "No sitting longer than 3 hours" keeps any one block realistic after a posting. "Subject level only" keeps the answer short enough to check. And the last line asks for the thing a week plan usually forgets: what gives way when an extra duty turns up.

How it was tested

One run on 7 November 2026, on free ChatGPT in a web browser, not signed in, in a temporary chat ^[2], so there was no saved memory or chat history to draw on. The model in use wasn't shown. The six checks were written down and saved before the prompt was sent.

1. No study block falls inside a posting (Monday to Saturday, 8 am to 2 pm), the Wednesday night duty (8 pm to 8 am), Thursday before 1 pm, after 11 pm on any day, or Saturday after 6 pm.
2. The week adds up to 17 hours, no more, and any totals it states match its own blocks.
3. Pathology and Pharmacology (marked 1) each get more hours than Microbiology (2), and Forensic Medicine (3) gets the fewest.
4. No single sitting is longer than 3 hours.
5. It says what to drop first when an extra duty comes up, and keeps time for the two weak subjects.
6. Subject level only: no topic lists inside any subject.

What came back

A full week was on screen in about 25 seconds: each day as a small table of times, subject and hours, a table of hours for each subject, a drop order and a short strategy.

Five of the six checks passed. Every weekday block sits after the posting, at 3:30 to 5:30 pm and 7 to 8 pm. Wednesday's study ends at 5:30, well before the 8 pm duty, with the line "No studying after night duty. Keep your energy for the shift." Thursday has no study at all. Saturday ends at 5:30 and Sunday runs 9 am to 6 pm. Nothing goes past 11 pm. The longest sitting is 2 hours. The weak subjects get the most time, and no topic is named inside any subject.

The drop order is clear: Forensic Medicine first, then one Microbiology session, Pharmacology or Pathology "only if absolutely necessary", and "Try not to sacrifice both weak subjects in the same week." It also added a line about not making up missed study by cutting sleep after the night duty or studying after 11 pm.

The catch

The sums. The heading says "17-hour weekly study plan", and the subject table starts "Total planned study time: 17 hours". Add up the days it printed: 3, 3, 2, 0, 3, 2 and 6. That is 19 hours. Its own subject table says so too: 7, 7, 4 and 1, "Total 19 hours".

To its credit, it noticed in the same answer: "Correction: The distribution above adds up to 19 hours, not 17." It named two hours to cut, Monday's Pharmacology and Sunday's Microbiology, and gave final totals of 7, 6, 3 and 1, which do make 17. But it didn't print the week again. The day-by-day timetable, the part you'd actually follow, still adds up to 19. Follow it as printed and the week is 2 hours over, and those 2 hours have to come from somewhere.

The fix is cheap. Add up the days yourself before you trust the week, and after any correction, ask it to print the whole week again with the change made.

Not one of the checks, but worth knowing: Thursday after 1 pm is left empty, and Sunday carries 6 hours. If Sunday is when you catch up on everything else, ask for a lighter Sunday by name.

The stamp

Half works · 7 Nov 2026 · free ChatGPT, in a browser · 5 of 6 checks passed. The week fits around the postings, the duty and the sleep after it, the weak subjects come first, and the drop order is clear. The days add up to 19 hours, not 17, and the correction didn't reach the timetable. Add up the hours yourself. One run is one run: try it with your own week and see what yours does.

Before you use it

For revising only. Never in an exam, and for marked work, follow your college's AI rules. ChatGPT is for ages 13 and over, or the minimum age in your country, and under 18 needs a parent's or guardian's permission ^[1].

The raw answer, word for word

Taken word for word from the page. The page shows each day and the totals as tables; here each table row is written on one line, with the parts split by a bar, bold and coloured labels are plain, nothing else changed. Screenshots are kept with the test log.

Here’s a balanced 17-hour weekly study plan designed around your MBBS postings, Wednesday night duty, Thursday recovery sleep, and Saturday evening break.

The priority is Pathology and Pharmacology because they are your weakest subjects. Microbiology gets moderate time, while Forensic Medicine gets maintenance time.

1. Weekly study timetable

All timings are study hours only. Breaks are not counted.

Monday
Time | Subject | Hours
3:30–5:30 pm | Pathology | 2
7:00–8:00 pm | Pharmacology | 1
Daily total |  | 3
Tuesday
Time | Subject | Hours
3:30–5:30 pm | Pharmacology | 2
7:00–8:00 pm | Microbiology | 1
Daily total |  | 3
Wednesday – Night duty
Time | Subject | Hours
3:30–5:30 pm | Pathology | 2
Daily total |  | 2

No studying after night duty. Keep your energy for the shift.

Thursday – Recovery day
Recovery protected

You sleep until 1 pm after night duty.

Time | Subject | Hours
1:00–8:00 pm | Rest, meals and personal time | 0
Daily total |  | 0

No study scheduled. Prioritise recovery.

Friday
Time | Subject | Hours
3:30–5:30 pm | Pharmacology | 2
7:00–8:00 pm | Pathology | 1
Daily total |  | 3
Saturday
Time | Subject | Hours
3:30–5:30 pm | Microbiology | 2
6 pm onwards | Free time | 0
Daily total |  | 2
Sunday
Time | Subject | Hours
9:00–11:00 am | Pathology | 2
11:30 am–1:30 pm | Pharmacology | 2
3:00–4:00 pm | Microbiology | 1
5:00–6:00 pm | Forensic Medicine | 1
Daily total |  | 6
2. Weekly subject-wise distribution

Total planned study time: 17 hours

Subject | Weekly hours | Priority
Pathology | 7 hours | High
Pharmacology | 7 hours | High
Microbiology | 4 hours | Moderate
Forensic Medicine | 1 hour | Maintenance
Total | 19 hours |

Correction: The distribution above adds up to 19 hours, not 17. To meet your exact 17-hour limit, remove:

Monday Pharmacology: 1 hour.

Sunday Microbiology: 1 hour.

Your final totals will be:

Subject | Final hours
Pathology | 7
Pharmacology | 6
Microbiology | 3
Forensic Medicine | 1
Grand total | 17
3. What to drop if an extra duty comes up

Use this priority order:

Drop Forensic Medicine first (1 hour). You're already relatively strong in it.

Drop one Microbiology session next.

Reduce Pharmacology or Pathology only if absolutely necessary.

Try not to sacrifice both weak subjects in the same week.

One important rule: Don't compensate for missed study by sacrificing sleep after night duty or studying after 11 pm.

4. Your weekly strategy

Pathology: Frequent exposure because it is currently a weak subject.

Pharmacology: Equal priority to Pathology; keep it consistent.

Microbiology: Maintain steady progress without overloading the week.

Forensic Medicine: A short weekly revision session should be sufficient for now.

Sunday: Your main study day, but keep the individual sessions within two hours.

The goal is consistency, not exhausting yourself. With postings six days a week and a night duty, a sustainable 17 hours is much better than an unrealistic timetable that you cannot maintain.
