Dear Rupam, Medical College Admission Test (MCAT) is an entrance exam to get into a medical college abroad. You are eligible for taking this exam if you attend a health professional school which includes Allopathic, Osteopathic, Podiatric and Veterinary Medicine. Students from US and Canada must have an Undergraduate degree to appear for MCAT. Other International students should be eiher pursuing or should have completed MBBS for appearing for MCAT. So with your B.Sc, you are not eligible for MCAT.
