Once upon a time, "arts" and "science" went hand in hand in higher education. You simply could not have one without the other. In point of fact, at Harvard University the college is still called "the College of Arts and Sciences." This reflects back to a day when "art" meant something more than smearing feces on a sidewalk.

If you received any university degree it was understood that your education was well rounded beyond your major field of study. It was this exposure to a greater universe of education than the particular college you spent most of your time in that gave rise to the name "unversity."

Instead of being on an "arts" v "sciences" track, students here were generally on a "vocational" v "academic" track. Students out of high school could opt for "trade school," or "votech" (contracted from vocational-technical), instead of "university," or they could go straight into the work-force with only a high school diploma (though with significantly diminished hopes for future success). The difference between votech and university was that in trade school you learned only what you needed for your chosen field, and consequently completed your studies in typically half the time (two years v four).

Of course, universities today offer associates degrees (one of my degrees is an A.Sc.), and institutions like ITT Tech offer bachelors degrees in three years or less. Thus the lines of distinction have been blurred, and this may be the source of the original poster's concerns. I can't speak to the issue in Malta, but here, a degree that ends with "science" would be less suspect than one that ends in something else. Such deviations from the standard vernacular typically (though not always) bely one of those "fast track" courses of study.

Of course, I suspect the original poster's question is more about beauracracy than education. (I am assuming his ambition is not to become a felon). I know that here in the States, if you want to be a licensed engineer you must pass a qualifying examination. The certifying organization doesn't care what degree you have as long as you have one and can pass the exam. On the other hand, if your degree is in psychology you aren't going to pass the exam. I don't know how it works in Malta.

And for that reason I will echo the advice that someone else has already offered. Consult your academic advisor.
