Hi all
I did an A Level in Chemistry last year and then rather than take A Level Bio this year did an Access Course and have conditional offers for Surrey and RVC. Rejections pre interview from Bristol (no idea why) and from Liverpool who essentially told me my work experience was in the bottom quotient.
Bear in mind with A Level there is a lot more to it than Access Course. I'm not saying its harder but there is far more content to cover and your learning is far more prescriptive. An Access Course basically covers what they believe you need to know for a regular science degree. A Levels are about measuring all your skills and differentiating 17 year olds in areas including memory, interpretation, intelligence, ability to apply yourself over two years. I ended up with a B on my A Level and took it in 7/8 months as an evening course. I would just say don't underestimate how difficult they can be to top out on (e.g. get an A) without a full time school background to rely on! Also check with your provider how many people got As - that should give you a good indication and will also reflect the quality of the content you are given and how closely it resembles the syllabus
