Hi Mithran,
Take the IELTS and other tests like SAT or ACT to be eligible to study abroad. You must write a very strong personal statement describing and explaining your CA choice, why you drooped it, challenges etc. And most importantly why you want to study Biology now after CA. Try to bridge the relevancy. Its going to be very challenging. Write to colleges abroad and prepare the application as per their rules and requirements.
