From Oxfords website (for Computer Science); For students taking the BTEC National Extended Diploma in IT, a conditional offer will normally be: DDD in the Extended Diploma and A* in A-level Maths.
Students taking BTEC National Extended Diplomas in science or engineering will also be considered, but the above requirement for A-level Maths still stands.
and Cambridge states; VCE A Levels, Applied A Levels, GNVQs and BTECs don’t provide an appropriate preparation for most Cambridge courses, where the emphasis is more academic than vocational. As such, these qualifications can’t, unless otherwise stated, be used to replace the required or highly desirable A Level subjects listed for each course.
However, if any required/highly desirable subjects are covered, a six unit VCE or Applied A Level could be taken instead of a third A Level or as an additional fourth broadening subject. This combination of A Levels and VCE or other qualifications may be acceptable for some courses.
Potential applicants taking these qualifications are advised to seek further advice from a College Admissions Tutor as early as possible.
BTECs and other Level 3 qualifications such as Cambridge Technicals are generally acceptable for admission to our Foundation Year, however there are some restrictions. Please see the course page for details.
