<p>You will also need to take 2 SAT subject test exams. In the states, you cannot take those on the same day that you take the SAT reasoning test. You will need to check the testing schedule offered in Australia. If it is the same as the US, then you can take the SAT reasoning test in June and the SAT subject tests in October. If you apply early action, then you will need to do well on those tests as you will not have time to retake for the early application cycle.</p>
<p>Of those schools, Harvard would have the best financial aid, no loans and equal access to financial aid for international students.</p>
<p>I am sure you can put something of interest together for the extracurricular section. Many Australian secondary schools do not offer the clubs and team sports that US schools do. If you were involved in any community based club teams, or have any developed personal interests, you should be able to expand upon those in the activities section. You should also explain in the additional information section what was actually offered by your school. They will read your application in context to your particular educational environment</p>
<p>Also, did you do the HSC (or other state based tests) or the IB? If you completed the state level exams, you will also need to include an explanation how those tests are graded.</p>
<p>Good luck!</p>
