Chances for being rescinded?

<p>I am an international student and have been accepted to Georgia Tech for Materials Sciences and Engineering. I got good grades in 3 of my 4 subjects (maths, physics, chemistry) in the mid-term and final report. A's in math and physics in mid-term, B in chemistry and an A in math in the final term, and B's in physics and chem. I know that this is obviously quite good (and my main reason for not being so tensed) but the problem lies with my 4th subject aka Literature. I failed in both the terms in the subject .
The problem is that being an international student i follow the UK system of education which has 13 years of high school instead of 12, so in the application i only submitted my grades for complete 12 years (in which i had a D in mid-terms and a C in finals for literature, A's and B's in the rest). So i was wondering whether i should be worried or not considering the fact that this is my least important subject and that i did well in all the others.
Any help would be greatly appreciated, thanks!</p>
