hi collin, glad that you made that switch to pursue your dream job. true i've many friends who are not doing what they are trained for. better to sacrifice one year for a more relevant course and career henceforth.
in fact, i wouldn't say you've wasted 1 yr of your time cos learning a new skill or knowledge is always handy, you can for example return to IT field not as programmer (and compete with armies of programmer from lower cost countries) but in biz development or govt regulatory fn.
enjoy your student life...the road to success is long but rewarding...
cheers,
mac,
