This is what cambridge said about this: 

On 4 January 2021, the UK Prime Minister announced new national restrictions for England, including the closure of schools and cancellation of most exams for June 2021.

As an international organisation based in the UK, we want to update our global community of schools on our position on the 2021 exam series following this announcement. A number of schools have asked if there will be any change in our policy.

We work with schools in 160 countries and most of our schools are telling us they want to run exams in June 2021 and expect to be able to do so, in line with guidance from their national and regional authorities.

We continue to prepare for the March and June series to go ahead. We believe that schools in most countries outside the UK, will want to proceed with exams as planned. We will continue to monitor the situation for the March and June 2021 series very closely and keep our schools informed but we expect exams to continue as planned where it is permitted and safe. Our priority continues to be to keep students safe and to make sure they can progress with their education.

This is honestly unacceptable. Today (6th of Jan) , the UK government has confirmed that there will be no alevel and gcse exams for their students. This is going to be so unfair for international students who are also competing to get into UK universities. How do we compete with people who already have a higher chance due to the possibility of their grades being inflated? CIE you can’t be silent, take measures, prove that you aren’t a racist and discriminatory board and do something that will prove there is equality in our education. We won’t be silent.
