Can I do a undergraduate degree in computer science and then go to medical school?

Yes you could do that, but only with certain universities, as some universities only accept particular degrees in their entry requirements (whereas other unis accept any degree). Also note that in the unis that do accept any degree, other applicants to graduate entry medicine courses who have a bio science degree or health science degree will have a competitive advantage. The best thing you can do to ensure your competitive edge with a computer science degree, is to get a first.

All the best.

Thanks for the reply, do you happen to know, if Canadian universities (particularly uaberta) accept any degree ?

Why haven't you just checked their course entry requirements online? I'm not really struck by your levels of enthusiasm and commitment, both of which would be prerequisites in the completion of successive maths and medical degrees.

Why not just do medical engineering or something like that instead?

Because I like both computer science and medicine (neurology), and the thing is that if I spend the undergrad years doing something I like (computer science) instead of something I don't like, it would be much better, wouldn't it?

Oh, so that's how it works over there. My previous advice is moot.

Just call up each and every university you're considering and ask them. That's the easiest way to find out what you need to know.

Canadian medical schools should normally require two introductory courses in physics, two in biology, and 4 in chemistry (2 general chem and 2 organic chem, or possibly 1 organic and 1 biochem), as they typically follow the US model (and hence a medical degree from Canada at an accredited university normally allows you to enter The Match and practice in the US without further study or qualification).

In the UK there are enough courses with different entry requirements that you will be able to find 4 that accept a CS degree. However, aiming for GEM instead of UG medicine is something of a mistake, I believe. GEM is MUCH more competitive than UG med (which is already very competitive) and you may need to apply several years running before you get in, even if you otherwise are a model candidate, simply because there are so few spaces on these courses (or you might need to apply for/enter into an UG course as a mature student).

That said, depending on what aspect of CS you're interested in you needn't necessarily get an UG degree in the subejct to pursue research in the area with a medical background. Bioinformatics applicants often are split between bio/medical background individuals and CS backgrounds, and the PhD programmes are inevitably tailored to the individual candidate anyway - they will ensure you have suitable training in relevant aspects of programming to ensure you can do your research (and vice versa with biology training for CS candidates, although arguably it's easier to teach programming than molecular biology).

I would suggest applying for medicine (possibly having some kind of bioinformatics leaning course as your 5th choice, if possible) and then intercalate in that area if possible or consider e.g. MBPhD opportunities, or doing a PhD later in your career after core training. It's not uncommon in some specialities to undertake an MD (the UK kind, a 2 year advised research programme) or sometimes PhD during training, typically after a couple years of specialty training, possibly maintaining some clinical attachments during the PhD depending on whether the programme is linked to a specific hospital or somesuch.

Thanks, that's a great advice but I don't like bioinformatics that much and I don't want to combine the two.

In that case all you're doing is "collecting degrees" which is pretty pointless. I would recommend you spend some time reflecting on what you are actually interested in pursuing as a career because you have a genuine personal interest in it, rather than some poor concept of "prestige" or potential to generate personal wealth.

In the undergrad years I have to choose any of the majors but I wanted to choose CS because that's what I like and also if circumstances arise that I cannot do medicine due to personal reasons I will still have a CS degree and can continue my life with it. I asked this question in the thread because I thought I can only do medicine related courses during undergrad.

My point is, if you're interested in medicine is there any particular reason you aren't applying to a standard UG medicine course in the UK, as opposed to studying GEM in the UK or abroad? It just needlessly extends an already long training period.

However yes in the US and Canada medicine is only a graduate course and any undergraduate major that has also fulfilled the premed course requirements would be eligible to apply. In some courses that's easier than others (e.g. Biochemistry and related courses), and you may find your flexibility in the course is somewhat limited as a result - also depending on course sequencing, it's possible you won't be able to take the MCAT until after you graduate and end up with a "glide year" as a result (typically if you aren't able to start the chemistry sequence until junior/3rd year of the standard 4 year bachelors course - this is unusual and can be avoided by ensuring you being the chemistry sequence as early as possible).

You could theoretically take the MCAT without having taken all the premed courses but you're likely to find it more difficult and have to invest more time and/or money in prepping for it to account for this. The only requirement is to have completed all the premed courses by the time you graduate, although if you have more than one or two to take in your final year (if you apply in penultimate year) they may be wary of offering you an acceptance.
