imo this discussion regards A level v Access is moot. Access is a vocational course that is vocationally led. it provides just enuff academia if u are going into a career like SW, for example (as i am).
i firmly believe that if u wanted to go read a science based degree, or indeed a classics degree at a redbrick...generally speaking (there will always be exceptions) an Access student would struggle, where an A level student probably wouldn't.
the only thing an Access course does is provide evidence to both uni's and oneself that confirms or belies potential ability that may or may not be borne out at uni.
have to be honest. at school, my teachers said i had the ability for oxbridge if i stopped messing about and worked. sadly i never did and now i have left it too late to read the sorta degree i wanted to read. today i am vocationally driven as well, and on my Access course i am sat amongst students that can barely string a coherent sentence together, certainly struggle with writing academically and incredibly, more often than not, don't seem to understand the material.
i'm not saying any of this to be big headed but to demonstrate a point regards access. my tutor says i have the highest level of understanding in my class. also says that the last time she had someone of my ability was 3 years ago. the point to mentioning this is as follows. i find what we do incredibly easy. where i struggle is crap time management and laziness due to boredom (sometimes) - i think this is because i'm on an access course. possibly, were i doing A levels. i'd be more stretched. ie, access is only challenging regards workload, not academically.
this is just my personal findings an view, mind. and i may well be incorrect. it's just to me, access is NOT as academic or as demanding as A levels. however it cannot be beaten as a foundation for vocationally led degree programmes and we have the advantage over any A level counterparts. again imo
