How important are IGCSEs for US universities?

<p>^^</p>

<p>I finished my IGCSEs a month ago as a sophomore. I already have an A* in Math (1 year accelerated). Here are some other IGCSEs I took - as well as my teachers' predicted grades and the final grades I think I got (6 = A, 7 = A*):</p>

<p>Further Pure Math 7, 7
Biology 6,6 or 7
Chemistry 7, 7
Physics 7,6 or 7
Economics 7,7
History probs 6 or 7, 6 or 7
Music probs 6 or 7, 6 or 7
English Language 6, 6 or 7
English Literature 6, 6
Foreign Language Mandarin 7, 7</p>

<p>So 11 IGCSEs in total; hoping something like 7/8 A*s.</p>

<p>How important are my IGCSE predicted grades? Will these have an impact or will they not matter as long as they are somewhat similar to my final grades?</p>

<p>Say I got 6's for all the subjects I predict I got '6 or 7' (so 5A's, 6A*s) and 2 As in Bio and Physics - will my chances for top math+science unis like MIT/Caltech drop significantly?</p>

<p>I will be taking IB next year:</p>

<p>Math HL
Chem HL
Physics HL
Economics SL
English Lit + Lang SL
Chinese B SL</p>

<p>I will get at least 43/45 for my predicted grades - most likely 6 for Eng, possibly another 6 from either Econ or Chinese.</p>

<p>Will also participate in AMC 12 next year and hopefully qualify for AIME; definitely cannot qualify (in terms of score - not a US citizen) for USAMO :(</p>

<p>Also considering that I will get good SAT scores (2300+/2400, 800 for Math II, Chem, Physics and possibly 700+ World History), how important will my IGCSE grades be? Can they mean the difference between an offer and a rejection? I slacked off during my sophomore year because of League of Legends addiction -_-; please give me your thoughts on how important my IGCSE grades will be. I am an Asian male international student (I heard this is a huge disadvantage).</p>

<p>Pls give me your opinion on my IGCSE grades when it comes to top schools like Princeton/MIT etc.</p>

<p>Also, what do you think would be the highest ranked 'safety' school for me in terms of numbers?</p>

how did it go?
