Am I going to be limited by doing a BTEC extended diploma instead of a-levels? Watch
With regards to universities, it can depend on the university and the course you wish to study.
For example, if you wanted to study BSc Optometry with us, you would need AAB in A-levels but you would need DDD + B (A-level) in the BTEC Ext. Diploma.
They are intended to be equivalent but aren't really in reality. Not all universities will accept them as equivalent, but it depends on the course. For example BTEC IT/CS in conjunction with A-level maths is considered sufficient for many CS courses. (including Oxford)
A levels used to be the gold standard and they are still accepted everywhere. Theres still a potential hierarchy with A levels.
BTEC are accepted in c75% of unis and courses. Courses where not accepted are things like Medicine and Engineering (make you do foundation).
You need to do some research and see what the entrance requirements are for the courses you wish to apply for at the unis you wish to attend. If you are applying to less competitive rather than elite unis, then you should be fine.
Good BTEC is better than poor A levels.
The fact you are already doing btec means its a bit late to change , so imo focus on getting good grades DDM up to D*D*D* and you should find plenty fo courses you can apply for at good unis. If you work hard it neednt limit you, although a small number of courses and unis may be harder to get into. make the best of it and work hard.
