Seeing that your score is quite high, it means you are more sincere.
Firstly, the mechanical and electrical majors can take some professional qualification certificates, such as lathe, milling, welder certificate, CNC operation, electrician certificate, etc. These are basically at the level of skilled workers, and it seems that they can be taken in school;
There is also a technician certificate, which is a higher level. Many teachers in higher vocational schools are technicians and the conditions are relatively high. You can search for relevant information;
Then there is the mechanical engineer, which generally requires examinations and reviews, and requires a certain number of years of work. After graduating from a junior college and working for three years, and having a bachelor's degree for one year, you can be evaluated as an assistant engineer, followed by engineers, senior engineers, professor-level senior engineers, etc. , the conditions are relatively high. When you reach the engineering stage, you need papers, patents, etc. This is basically the highest honor in mechanical studies;
You can also take some professional certificates, such as UG, PROE and other software There is also a certificate for operation, which is a demonstration of your application level of these software. The test is recognized globally. Some foreign companies and large companies recognize this. Generally, you need to pay for training and then pass the test to get it.
There is a difference between those who study mechanics and those who study architecture. These certificates have no direct value. As you said, those who study architecture can earn thousands of dollars a month by becoming a second-level construction engineer and working for other companies. Mechanical ones generally cannot reach this level. Of course, there are times when individual companies need it, but it is not as common as in the construction industry. It may be good to give you a few hundred for others to use. Because construction has requirements, some large-scale projects will look at your certificate when bidding, and use this as a sign of strength. Therefore, many construction companies do not have so many engineers. They are all migrant workers engaged in construction, so they Just spend money to buy these certificates, which are for temporary use and will be returned to you when they are used up. Mechanical work requires experience and ability. A certificate only shows that you have the relevant skills and level. If you have the level, you can still make a lot of money without a certificate.
If you are taking the postgraduate entrance examination at a junior college, the state stipulates that you can apply for the postgraduate entrance examination with the same academic qualifications after 2 years of graduation, but most schools have more stringent requirements, such as a fourth-level certificate, published papers, and several courses. Transcripts, etc. To put it bluntly, you are restricted from taking the college entrance examination and you are not welcome. Even if you meet the conditions and pass the preliminary examination, you will basically not be able to pass the re-examination. Of course, it is another matter if you are very good. A few schools only need to meet national requirements. These schools are generally ordinary schools, and most of them are in relatively remote places, such as the Midwest.
The electromechanical postgraduate entrance examination generally tests mechanical design, mechanical principles, material mechanics, theoretical mechanics, microcomputer principles, etc. Choose 2 subjects from them. This depends on the school’s specific admissions brochure. If you want to take the exam, you must first choose a school to see if you can meet the requirements. It is best to contact the school's admissions office and talk about your situation. After confirming the school, prepare for the exam according to the school's admission brochure. Of course, you can also take the postgraduate entrance examination after obtaining your undergraduate diploma, so there are not so many restrictions.
There are many paths to choose from in life. The key is to act according to your own circumstances.
