I applied to UCL, KCL and LSE at the beginning of January, all online. However it took me a while to get the references together and it is only in the last week that all three are processing them. My question is: do the universities start to consider applications when they are submitted or only when all the supporting documents are received?

Will an application submitted in January, but references sent in February be treated exactly the same as an application submitted in February along with the references?

Thanks
