What should I, a multinational high school dropout, do?

<p>Okay.</p>

<p>Right now I'm 18, so late senior age (or at least that's the way I'd like to think of it). </p>

<p>I'd love to pursue a degree in something like Neuroscience, Organic Chemistry, Physics, Mathematics, perhaps Computer Science, but I think I'd prefer to continue what I'm doing now; learning random object oriented languages. </p>

<p>Recently (a few months ago) someone suggested that I take some college entrance exams (SAT, ACT, etcetera) to provide some evidence of education, even if it was entirely self administered. </p>

<p>I took an SAT practice test at a tutoring company, along with the free online College Board released exam (scored perfectly in Math on that particular test) and scored in the area of 2200 on both, so not dreadful, but I'm hopping to get at least a 2300 this June, or score perfectly in Math; something that makes me stand out. </p>

<p>In addition I decided to take some AP exams this past May, Calculus AB (I had registered for BC but the school made a mistake with my registration), Chemistry and Biology. </p>

<p>I didn't really study for any of them (other than a practice test or two per course) or take the courses, but I'm confident that I passed all of them and scored a 5 on the Biology (or at least 100% in the FRQ section and 85%< in the multiple choice section), a 4 or better for Chemistry and a 3 or 4 for Calculus AB (I know, I know, but in my defense, I was sick with the flu that day). </p>

<p>Currently I'm back in Australia, and am registered for the STAT and SAT here and Macquarie university (Sort of a B-rate Australian University for anyone who's interested) seems like it'd accept me (Based on speaking with admissions) ... contingent upon a 90< percentile score on the STAT. </p>

<p>So... let's say that I get into Macquarie, should I go there? If so, how would I transfer to an American College? Would there be additional requirements? Would it be harder to transfer from an Australian University as opposed to a CC in America? </p>

<p>What should I do?</p>

<p>Do you have anything that would equivalent to what you would receive upon high school graduation?</p>

<p>Not really. I mean, I took the CHSPE (California High School Proficiency Exam), but really that just makes me exempt from taking classes, so that I could drop out and work legally.</p>

<p>I could take the GED, which shouldn’t be THAT hard. </p>

<p>I wonder if that would actually have any bearing on my application though. Also, I’d think that a 2100< SAT score would show any prospective college that I’m capable of passing the GED. I’m not certain of the legalities behind it though.</p>

<p>Really, I’m just wondering if I should go to College here or wait for America (Spring semester)? What chances would I have applying to a place like Harvey Mudd or Caltech, or worst case scenario (I’m sure it’s not, Haha) USC?</p>

<p>Given that you messed around in high school, I think that you should tone down your expectations and not apply to places like Cal Tech. I highly doubt that you would be accepted.</p>

<p>Macquarie sounds like a the better option.</p>
