No, they are different things that share an acronym. Cambridge asks all applicants to complete an additional questionnaire (historically called the SAQ, the Supplementary Application Questionnaire, now part of the My Cambridge Application), which is separate from veterinary selection. For veterinary medicine specifically, Cambridge selects using the ESAT and interviews.
The veterinary Supplementary Assessment Questionnaire we help with is the scored SAQ used by Bristol. If you are applying to Cambridge for veterinary medicine, ask us about ESAT and interview preparation instead.
