It's an international undergraduate, and many universities have it. What is 2+2, 1+3, 4+0? To put it simply, studying in China 1-3 years. Those who complete their studies and pass the exam can get a domestic diploma, and then study abroad for 1-3 years, get a foreign undergraduate diploma and get a degree certificate. These international undergraduate programs are not unified by the state, so they do not pay attention to the results of the college entrance examination. For failing in the college entrance examination, I got good grades in English and went to the last international conference.
