My reputation can't be maintained. The work in the 4th year is relatively free. Passed the 1st Grade Civil Engineering 1st Exam Didn't study hard for the 1st Grade Civil Engineering 2nd Exam, studied hard for 2 weeks before the exam, and the result was 50/50 Studied for the 2nd Grade Civil Engineering 2nd Exam starting 2 weeks before the exam. Thanks to this book, I feel quite confident. It contains 12 years' worth of past questions, so I worked through them thoroughly. Therefore, there is some wear and tear. However, there are no writings. The results haven't been announced yet, but I'm selling it because I don't have money to buy winter tires. It's too embarrassing to not have the 2nd Grade Civil Engineering qualification in the 5th year, so I pray that I pass. If I fail, I will quit my job.
