Although I haven't studied in London or Coventry, I have heard from the British that WMG has a good reputation, which I think makes sense.
WMG University is great. It and WBS are called the two richest universities in Warwick. The quality of education is very good, but studying is really hard (nine to six is not bragging). WMG has established extensive cooperative relations with major enterprises and business groups in the UK. Enterprise executives participate in teaching, and teaching simulates the operation of the company. Students generally report that the learning effect is very good.
Which is better than UCL? It depends on your specific major. Warwick's WMG Engineering Business Management (EBM) is very good, and BMW's HR also graduated from this major; E-commerce is great, ranking first in the world this year (pictured)
However, the tree attracts the wind, because it needs strict typical width in and strict out. A year ago, a large number of China people hung up their graduation thesis, and then these people's revenge tendency, you know. . . But don't worry, it is no problem to study hard and graduate ~
