Should I Retake My A-Levels

<p>hey there, i just got my A-Levels results but they were quite disappointing.. I mean i got like a B, 2C's for 3 marks each and a D in chemistry.. i got C's in maths and physics... currently i just graduated highschool, and i'm not even 18.. most of the people in my class are 18.. while some are 19.. as my results are not satisfactory i was wondering if i should retake my A-Levels during the May/June 2015 session.. any opinion on that matter would be helpful.. thanks!</p>

<p>P.S. i'm planning to apply to a U.S state university...</p>
