In simple terms, the offer rate is the percentage of applicants who get offers, and the acceptance rate is the percentage of applicants who are finally accepted.

So why are the two often so different? There are three reasons:

1. The offer you get first is conditional. Undergraduate applications in the UK generally start one year in advance, so when submitting applications, applicants generally submit estimated grades. In this case, the British university will first issue a conditional offer, which will list the academic conditions that the applicant must meet to get the final admission, such as language, academic certificate, payment, etc. If the applicant fails to meet the conditions listed in the admission at the end, the final admission will not be granted.

2. Most people do not apply to just one institution. When applicants get offers from more than one university, they will naturally choose to give up offers from some of them, which also affects the final acceptance rate.

3. The competition is intense. The basic application requirements of some universities are not high, but due to the large number of applicants, the final admission conditions exceed the applicants' expectations, resulting in a drop in the admission rate.

In short, getting an offer does not mean that you will eventually be admitted to the university, but you still have to be mentally prepared.
