Direct answer. Define the question, methods, non-negotiable curriculum signals, evidence gaps, nearest alternative and external constraints before narrowing to institutions.
- 01
What question would I still want to investigate after the first difficult semester? - 02
Which methods do I want to practise repeatedly, not merely read about? - 03
What compulsory modules would make me rule a programme in or out? - 04
Which claims on the programme page need a current institutional or regulatory source? - 05
What is the nearest alternative field, and what would I lose by choosing it? - 06
Which location, accreditation, placement or language conditions could materially change the decision?
What not to write
Avoid unsupported probability estimates, vague prestige language and conclusions copied from a ranking table. If a claim can change — entry requirements, fees, accreditation, placement arrangements or course availability — attach the current responsible source and the date you checked it.
Use the note as a revision record
Keep rejected alternatives and the evidence that changed your view. A strong decision note is allowed to end with two plausible directions; uncertainty is more useful than a forced “perfect match”.
