You don't need a high degree to learn technology. General skills such as beauty salons and pastry chefs can be learned as long as there are snacks. But the high-tech ones with high technology content, such as computers, programming and design software, just do more work. However, I still suggest that although I don't go to school, I can take some adult exams, self-study exams and online education to improve my academic qualifications. After all, this society is a society where undergraduates catch a lot, and many places still need thresholds. Among the above methods to improve academic qualifications, passing the exam is the simplest, most time-saving and most convenient method. If you want to improve, you can consult he cheng Vocational Training School, where I took my second degree, which is quite responsible.
