Oh wow, I thought this thread died months ago and now I login and find I missed all these new comments. Sorry guys! Thanks to dugefaellstmir for your input, and Sk2001 for your message
Yes! I graduated with a first class honours. And I'm not entirely sure what GEM is, so I'm going to say no.
There are so many possibilities! A lot of people go into further research (masters, and then PhD, with the intention of continuing into a research career and possibly lecturing). At the same time, a lot go into consulting or finance. Some stay in science, but not research (e.g. medical consulting, or the management side of pharmaceuticals). There are a ton of new biotech companies emerging, particularly in London, so I know a few friends who have signed up for that kind of thing. And some go into patent law. I also have friends who have switched into fields like biomedical engineering, or computer science (from a neuroscience perspective).
A lot of people make the mistake of thinking you're bound by the field of your degree, but the possibilities are endless! I'm personally looking into pharmaceutical careers (considering both research and quality control/operations pathways).
Yes! There is a fair amount of maths, not so much in first year (although Professor Drickamer does some stuff on deriving equations, and Dr Beis covers some maths on reaction rates), but in my second year we covered protein crystallography which was essentially applied maths and physics. I'm not sure how it works now, since they've dramatically changed the layout of second year since we did it (now there are optional modules and a tutored dissertation).
Biotechnology and biochemistry are exactly the same degree for the first two years. In the third year, there are certain modules that have "biotechnology credits" and if you pick those particular modules you graduate with a biotechnology degree rather than biochemistry. I have a friend who did biotechnology, and her third year modules were stem cells, cancer, and neuroscience - none of which had any maths (except a little bit in neuroscience) so I don't think the biotechnology stream is more quantitative. I can't say anything about the UCL course - you would have to get in touch with the course directors.
I'm doing a masters at UCL now, but it's hard to compare two universities based on an undergraduate experience at one and a postgraduate experience at another. Are you deciding between the two universities?
I'm looking into pharmaceuticals, but as I said in my reply above to uka_qwer, there are a huge range of possibilities and doing a biochemistry degree doesn't tie you down to lab based careers. Where did you get the idea that biochemistry isn't a respected degree? From my experience, science degrees are generally very highly regarded.
At Imperial, biology isn't a required A level for those wanting to study biochemistry. There's quite a lot of biology in the course, so you would undoubtedly find things harder (at least to begin with) than your peers just because you wouldn't be familiar with a lot of the biological concepts.
That said, I think you can generally trust that entry requirements are sensible - if they don't specify that you need A level biology to get in, the course is doable without A level biology. I have friends who came in without basic biology knowledge, and it just means you have to be willing to put in the extra work to catch up. At the same time, most people don't do physics at A level, and struggle with the physical aspects of the biochemistry course - so you will have some advantages too.
Of course, this advice is specific to Imperial. If you have particular universities you are interested in, definitely check their entry requirements for biochemistry or get in touch with the admissions team for advice.
