How important are my school records as compared to my results in major exams?(GCE A levels, SAT etc)

<p>Hi, I'm a Singaporean student studying in Singapore and I'll be taking my GCE A levels this year. I have a rough gauge of where I want to be after my examinations, but before deciding on anything I would like to explore some options in overseas universities (especially in the states) such as UCLA, Berkeley, Brown etc. I am interested in studying psychology or biomedical sciences.
Was just wondering how important are my school results as compared to my results in A levels? See I'm not exactly the best student, and I admit I had a rocky start with JC, but I have shown tremendous improvement throughout my exams in school. My subject combination is as follows :
H2 Biology
H2 Chemistry
H2 Mathematics
H1 Geography
H1 General Paper
And during my recent prelims, I have scored straight A's for the above mentioned subjects.
However, I'm worried that the initial bad results in school would pull down my chances should I decide to apply for an overseas university in U.S.
I would really be open to all criticism and advice from everyone, hopefully someone could just shed some light on how important academic results in school are important as compared to A level results?
Thank you! </p>

<p>can you give us more information about your GPA and test results?</p>

<p>School grades are more important than exams in general…for example, if student A has 4.0 unweighted GPA and 2000 SAT, that’s not bad. On the other hand, a student B with SAT 2300 but GPA 3.5 or lower wont be evaluated nicely.</p>

<p>American universities typically want to have your IGCSE’s/OLevel results + your AS results + your predicted A Level results. Since most British-patterned schools don’t release other grades than these, those would be the most important, along with your SAT/ACT score.</p>
