The phrase "No change" indicates that the original sentence about how preparation time for exams is determined is already correctly structured without needing alterations. The use of "knowledge" on its own is a neutral and inclusive term, making it applicable to anyone regardless of perspective.

Considering the other options: "his/her knowledge," "their knowledge," and "your knowledge" all attempt to personalize or generalize the statement in ways that might not fit every reader's perspective.

For instance, "his/her knowledge" may imply a specific individual, which limits the inclusivity of the statement. "Their knowledge" while more inclusive than "his/her," could still imply a group, which may not be appropriate in every context. "Your knowledge" specifically addresses the reader directly, making it less general and potentially less relatable.

Thus, keeping the original sentence as it is maintains its universal applicability to anyone preparing for exams, which is why "No change" is the most suitable answer.
