- These durations are approximate and depend on the programme and research progress.
- None of them promises that you will be admitted straight after BTech.
- In Singapore, check each department's bachelor's-entry rules.
My Advice
Pick the country by your research area, funding and fit with a supervisor, not only by the number of years. Before you plan for the 2027 or 2028 intake, read each department's own page to see whether it accepts students straight after a bachelor's degree.
