10.I was always told that the three Ps---patience,positive thinking and perseverance,were a sure path( 61)tosuccess.But this advice does not always work as planned.My high school maths exam is one example.The exam,(62)whichwas originally to be held in our classroom,was changed to the library at the last minute.This,however,didn't bother me because maths had always been my( 63)stongest(strong) subject.I patiently walked to the library,(64)took(take) my seat and did some deep breathing to help relax( 65)myself( I ).But my mood changed quickly when I saw(66)the first question.I had no idea(67)how to do it.I tried to stay positive and persevered until I finally found the solution.With the problem(68)solved(solve),I felt proud of my (69)achievement(achieve)(70)Unfortunately(fortunate),I then noticed that I had just 10minutes left to complete the rest.
