Answer 1

Can you try with changing the view to this?
SELECT TOP (100) PERCENT
AP.ID,
AP.FirstName,
AP.LastName,
AP.Branch,
AP.EnquiryID,
AC.Name,
AI.College,
AI.Mobile,
AP.ExamID,
AP.EntranceID,
AP.RegNo,
AP.VenueID,
AP.Exam,
AI.Gender,
AP.BranchID,
AP.CourseID,
AP.CreatedDate,
AI.Status,
AP.Entrance,
AP.Venue
FROM dbo.AGAM_AceOFPace AS AP
INNER JOIN dbo.AGAM_Inquiry AS AI ON AI.ID = AP.EnquiryID
INNER JOIN dbo.AGAM_Course as AC on AC.ID = AP.CourseId
ORDER BY AP.EnquiryID

Answer 2

Do you have an index on EnquiryId and CourseID?
Seeing as you are joining, ordering and partitioning by it you really should.
CREATE INDEX IDX_AGAM_AceOFPace_EnquiryID
ON AGAM_AceOFPace (EnquiryID)
CREATE INDEX IDX_AGAM_AceOFPace_CourseID
ON AGAM_AceOFPace (CourseID)
