* BSc (Bachelor of Science): 3-4 years
* MSc (Master of Science): 1-2 years (often 2 years for a thesis-based program)
* PhD (Doctor of Philosophy): 4-7 years (often 5-6 years)
Therefore, a total of 8 to 13 years is a reasonable range to expect. The PhD phase is the most variable, as it depends heavily on research progress and thesis writing.
