<p>I think you are a little confused about how the O level/A level and American systems mesh.</p>
<p>In America, we call the last 4 years of secondary education, grades 9 - 12, which happen in years 10 - 13 “high school”. The reason that the grades and year levels don’t match is that what many countries call “Year 1”, Americans call “Kindergarten”. The next 4 years are called “college” and are also the beginning of a university education.</p>
<p>In some other countries, including England, they call the last two years (years 12 and 13) “college”, but they’re the equivalent of the last two years of high school. The O levels or GCSE are equivalent to 10th grade, the mid point in American High School. Just like you can’t go to University in England or other countries with just O levels or GCSE, you can’t go to an American University with just O levels or GCSE any more than you could go directly from the American 10th grade. </p>
<p>You aren’t being asked to take a “gap” year a gap year is when someone takes a year off after completing high school. By American standards, you haven’t completed high school. You’ve got a couple more years to go. You can meet this requirement by doing A level courses (“college” in your vocabulary, “high school” in American), or by completing an IB diploma, or by coming and studying in a high school or equivalent in the U.S… </p>
<p>Staying home and completing the A Levels is almost guaranteed to be the less expensive option. If money isn’t an issue, coming to the US and studying in a boarding school, either one that serves US students too, or a program like the one in New Hampshire that seems to be just for international students. Doing that, and having an American transcript might give you a subtle advantage, but it’s not huge and may not be worth the price difference.</p>
<p>As far as junior college or community college, those are equivalent to the first two years of uni in the British system, although they are often open to students with less education credentials. Generally you wouldn’t go to CC without a high school diploma (A levels/IB).</p>
<p>If you are truly interested in a American college (read uni) program now, one option would be to look at “early college” programs that are set up for students who skip part of high school. Simon’s Rock at Bard is one such program to investigate.</p>
