Academic certification is very important for every student studying abroad, and it is an important certificate that international students must provide when they return to China to take the entrance examination for banks, civil servants, state-owned enterprises and institutions, large foreign companies and doctoral students. Students studying in Britain need different materials from other students. The difference lies in visas, which are divided into paper visas and visa cards. Ordinary visa card was renewed after the expiration of the previous paper visa. This is a small pink card with a chip on the back. The card has information such as personal signature and weekly working hours. In addition, academic certification is not only to examine the authenticity and validity of students' final degree, but also to comprehensively evaluate students' entire study abroad experience. Many evaluation criteria include: study time, visa type, teaching method, teaching place, etc. There are high requirements for the continuity and cohesion of the whole learning experience. Of course, there are other special circumstances that need specific analysis!
