<p>Wow - three completely different fields!</p>
<p>First, don’t worry about your age. Second, there’s nothing irresponsible about recognising you need more education to get a job. Now…</p>
<p>You can probably do the IE degree in 3 years or less. Since you have a BA already there’s a good chance you’ll be able to get your core requirements either waived entirely (if you go to the same schools again) or covered by transfer credit. You might be able to shorten the calender time by doing full time summers as well (I know that Auburn for example has a 3 year engineering curriculum that does this) but you could also be screwed time-wise by required “sequences” in math and the sciences.</p>
<p>Nursing - Mrs. C has been a nurse for better than 25 years so I know a little about the field. Administrative jobs are few and far between; expect to do 3-5 years “in the trenches” so to speak. You’ll want to be very sure you want to be a nurse before you start on this path - you’ll have literally life-or-death responsibility and almost no power. Keep in mind too that administrators often end up filling in when regular staff don’t show up and the pool is already over-commited. On the upside, this is the least math-intensive of the three options.</p>
<p>Accounting - I know little about the field, though as a History major you may have some substantial catching up to do in math (though probably not as much as IE).</p>
<p>Finally, since you already have a BA, you might consider one of the many very good “certificate” type Masters programs at a reputable university that are designed specifically for folks like you who need a marketable piece of paper to get their foot in the door. They generally take only 1 academic year (as opposed to the 2 years a regular MBA takes for example), but the downside is that the best of them have extremely competitive admissions. You may also need to take the GRE or GMAT for some of them.</p>
<p>Good luck!</p>
