From what I've heard, Access courses are NOT a 'back door' into uni. They're actually quite difficult, as the workload is so intense. After all, you're expected to learn two years worth of A-level standard stuff in one year. In fact, from speaking to others who have done Access courses, it is people with the 'it's just a quick and easy route into uni' attitude that actually end up dropping out or failing the course, simply because they massively underestimated how hard the course would be. They are level 3 standard, which is equivalent to A levels. They. Are. Not. Easy. Nor are they a nice easy route into uni. They're an excellent way to secure a uni place, IF you are willing to work hard and achieve good grades. If you enter it assuming you'll just breeze through, you will fail. Access courses also have exams.
I smell a troll, to be honest.
