Preparing for MCSD

Today, I made up my mind to take the MCSD test. I thought I was a junior. I didn't even have a certificate in my hand. I was very depressed. My girlfriend has been taking the sun certification for a long time. I think I should also take the certification and not take the postgraduate entrance exam. When I graduate, if I still cannot get the legendary degree certificate, the University will not be in vain. Today I studied the Microsoft certification examination courses and decided to prepare for them in half a year (four core courses and one elective course). If I don't know if I can pass the exam, I will cry if I cannot pass the exam, so many registration fees, plus a lot of reference fees, can only be depressed if you cannot pass.
The following are the test lists and course reference books of the micro-MCSD soft certification I have prepared. They are officially recommended by Microsoft, and I don't know if I can buy a Chinese photocopy version. Have you ever obtained any comments from anyone who has passed Microsoft certification? I can also learn it later.
