<p>I think that Business at UT or McGill would be more portable. It’s also rather easy to work in Canada but you’d be an immigrant, so not as easy as working in the UK. Then it’d depend on whether you speak French and would be able to become bilingual (big plus) or would be hindered by the bilingual nature of Montreal - certainly everyone speaks English well, but not speaking French is a definite handicap. UT is closer to English Unis and you wouldn’t need to learn French, which can be a plus or a minus depending on what you’d want to specialize in (although not speaking French even outside Quebec is not tops).
However, if you can get a First at UCL then job in a London company, that’s what would matter for getting into a top MBA (assuming you retain your test taking skills).
Finally, there’s the cultural discovery factor, that must have motivated you to apply to UT and McGill, right?
So if you’d rather go abroad, go to Canada, if you’d rather stay in the UK go to UCL.</p>
<p>As an international, your odds in the Ivy League are about 3-4%. Your 44 will not help you much because the decision will not depend on it and may even hurt you if you appear as a “drone” ie., if that’s all you have. Now if you also have conducted research, have a Gold Duke of Edinburgh Award, and were rugby captain, plus 2200 on the SAT’s, things would be different and your odds would get to 10%.</p>
<p>But why would you even want to? Seriously, in the US, what matters is FIRST how well you do at the school and in the subject/course you chose. For the MBA, the job you had and how well you did it will factor heavily too. You <em>will</em> need quantitative skills though so make sure to stay on top of basic maths, stats, probabilities, etc. it will be expected you’ll have taken Calculus (roughly, A Level Maths, not Further Maths).</p>
