Advantages: the country can change and the major can be chosen. 68 universities. 25 in Britain and 20 in the United States. Education management is strict. High rate of going abroad and good reputation.
Disadvantages: only 3-4 years of school education. The registration office is simple (but this is not very important, depending on the project itself), and the project only needs 1+3.
Shanghai Overseas College 1+3 and 2+3 projects. You must select a country before entering, and it cannot be changed. The class place is in the building opposite Shanghai University, not in the school, and the teacher is also a teacher of Shanghai University, which makes no difference. They are mainly engaged in projects in New Zealand. It seems that the rate of going abroad is not very good, let alone management.
Advantages: There are many projects in New Zealand, Japan and South Korea, and the running time is long.
Disadvantages: lax management and poor quality of teachers. There is something wrong with the rate of going abroad. In fact, the project itself is too single to choose, UK 2, USA 2, Canada 1.
Maybe you are comparing the programs of two colleges. Diplomas in both programs can be recognized by the state. Personally, I suggest going to Shanghai to find Lee Tae. I always listen to introductions from other teachers and parents, so that I can get to know them.
I must say a few words about overseas colleges. I always attack education groups, overseas training centers and so on. I think others are bad. They all belong to the same university, and their quality can be seen from here.
