Diana left public school in 1977. While she departed from her public school education at that time, she subsequently completed her formal education.
Upon leaving public school, Diana, then 16 years old, continued her studies for a few months at a finishing school located in Switzerland. During her time there, she not only completed her formal education but also developed a notable skill as a competent skier.
To provide a clearer overview of her education timeline based on available information:
| Event | Year/Age | Detail |
|---|---|---|
| Left public school | 1977 | Marked the end of her public school attendance |
| Completed formal education | Age 16 | After attending a finishing school in Switzerland |
| Developed skiing proficiency | Age 16 | Achieved during her time at the finishing school |
This progression indicates that while she left a specific type of institution (public school) in 1977, her educational journey concluded with the completion of her formal studies in Switzerland, rather than an outright "dropping out" of all education.
