Having done both AS and coming to the end of my BTEC extended diploma in medical science I can safely say that none of this is true.
I left after a year of AS due to illness and bad quality teaching and as it was so late in the year I was not able to get into another sixth form for September entry, I was able to get a place on a BTEC course that would allow me to progress onto my chosen degree course.
Shortly after beginning my BTEC I discovered the limitations of A-levels. The syllabus is extremely limited and only really skims the surface of the subjects, you are not encouraged to learn and think for yourself as the main priority is getting you to churn out the same information as everyone else in the country in the exact same way the examiners want. A levels are not a test of knowledge but a test of how well you can regurgitate the syllabus.
I found that a BTEC challenged me much more, I was free to do background reading and research for assignments and I could make them as detailed and as complex as I wished them to be and I would not be penalized for it. My knowledge on the subject only grew and it quickly surpassed those of my peers still doing A-levels. My practical experience is far more detailed than those doing A levels, in A-levels the nice technician will set everything up for you and then at the end you are not even expected to write it up properly. I have been able to write professional, well-structured and properly researched lab reports (including referencing other scientific papers) r 2 years now whilst my peers that went to uni struggled with that aspect. The experiments are relatively basic with A-levels (mainly because the syllabus does not require complex experiments and the majority of schools are limited in terms of facilities) whereas the experiments are a lot more complex and are actually applicable in a real lab environment. Last year one of my modules involved us having to plan, write up and conduct our own experiments with no teacher involvement whatsoever, a lot of people I know doing A-levels would have struggled with this as there was no teacher safety net to tell them what to do. I ended up choosing a microbiology experiment (investigating antibiotic producing colonies in soil samples) that would not have been possible in a school environment, In a school lab I would not have been allowed to use E.coli or S.albus or to even open the plates that contained colonies of bacteria but because our labs have the necessary equipment and we are encouraged to work independently, I successfully completed the experiment and got the highest grade in the class.
The argument that we do just one subject is not entirely true, we just go into more depth and detail than an AS does in that particular subject. For instance the degree I have applied to do required A-levels in Chemistry, Biology and another science subject. The modules for my particular BTEC include Maths/statistics, Physics (including medical physics), Biology (Physiology, Genetics, Regulation of body systems, reproduction and we touched on many other subjects such as Biotechnology and immunology), Biochemistry, Chemistry, Health and safety in laboratories (applicable for the industry we are being prepared to go into), How these large scale scientific companies work and the processes behind how they are managed and run (so essentially we have done a little Business) and we've even done a little philosophy. So essentially I am quite well covered for my degree and I have a much broader and in-depth knowledge than when I did AS.
as a result I have 4 offers from Uni's (3 of which are Russell group universities) and i am well on my way to meeting these offers.
BTECs set you up far better for later life and as a result I have learnt a lot of skills that will help me at uni. I am able to work independently and do not require a teacher to tell or show me what to do. I am able to think for myself. I have more practical experience and my skills in the laboratory are far more developed than those doing A levels. I am also hugely effective at managing my time (having 4 assignments due in one one day and having 2 weeks to complete them all is common).
In response to the BTECS being easy argument all I can say is they are as hard as you want them to be. Some people in my class do not care for their final grade so they do minimal effort whereas the people that want to work hard constantly work hard throughout the 2 years instead of in the weeks leading up to exams. Timing is very tight and in order to do well you have to work hard, far harder than I worked at AS. The majority of my assignments are over 10,000 words which is practically a dissertation whereas the homework I got for AS was a couple of pages at most. Generally, I do not find the work difficult but I am a dedicated student who puts in a lot of hours to background reading and research and have worked hard from the beginning. However, some of the content in the modules was touched on briefly at AS so perhaps that is why I don't find it difficult as I have already done it before.
I just find it funny how I and many other people I know doing BTECS are easily getting uni offers including those from Russell group universities whereas the majority of people I went to school with not only missed their firm but their insurance choice too.
Why shouldn't we be allowed to go to Russell group uni's? We are not against working hard, we are very much used to it. Perhaps more than you A-levels lot are. Just because we are dedicated and able to succeed does not mean we should be penalized because we are going about it the alternative way. We haven't taken the 'easy way out'! All this whinging about us stealing your university places is ridiculous! either be quiet or go work harder to improve your grades, just like we have worked hard to improve ours.
A levels are a walk in the park really
