In that case it depends what you are interested in,
and on the curriculae.
The business admin aspect is probably going to stand
out more for potential employers, and they will likely
see the IT part as an 'extra', rather than indicating
any real experience/knowledge of IT.
If what you want is to get into IT, then look for a
straight IT type course. You'll learn more, and it will
look better to IT employers.
This is all just my opinion, of course.
In the past I've suggested that students go for what
interests them, that way whatever career they go for
(relevant to qualifications) will be more satisfying.
There's nothing worse than being wedged down a career
path just because it seems like a good earner, only to
find that you hate it.
