<p>Major: History but changed to Biochemistry</p>

<p>I go to UCR. I am planning to tranfer out to University of Chicago, UCLA, UCSD, EMORY, and DUKE. My high school stat and first year at college wasn't that great. I had 2.4 and 2.2 in first two quarters. I changed my major to BIOCHEM becauase of personal reasons, and I am going to use them on my personal statement. I have strong reason why I changed my major to biochemisty and planning to go to med-school. Anyway... I have 4.00 GPA on all science classes (except one hummanity science class(c+)). What are my chances? Do I need to retake SATs? and what do I need to do to make it better?</p>
