The phrase "got through the examination" is commonly used in English to indicate successfully completing or passing a test or assessment, even if the outcome was unexpected. In this context, the word "through" implies that the individual navigated the challenges of the examination and came out on the other side, which aligns well with the phrase "to everyone's surprise." This suggests that the result was unexpected, highlighting that the individual may not have been anticipated to succeed.

Let's consider the other options.

- **A) over**: This phrase typically indicates something has been completed, but it is not commonly used with examinations in this context.
- **B) passed**: While "passed the examination" is correct, it lacks the nuance of surprise and experience conveyed by "got through."
- **D) failed**: This option contradicts the intent behind "to everyone's surprise," as it implies a negative outcome that wouldn’t typically be seen as surprising in a positive light.

Thus, "got through" effectively conveys the unexpected nature of successfully completing the exam, making it the most appropriate choice in this context.
