congratulations! Be prepared to study, if you don't understand something look it up, utillize the study guides that come with the book, when you read the review questions read the rationales, if you miss any questions on your exams review the exam and learn from the mistakes, all of the information builds on itself. How you study and what you study depends on your academic background. utilize your lab and clinical time to gain hands on practical knowledge, your instructors will take notice. Don't let yourself hang out with negative classmates on a regular basis, most important you can't pass by memorizing, read it, think about, and do your best to understand and comprehend the information.. It also helps to familarize yourself with how the books are designed to help you learn. Don't fall behind on your reading.
hope this help.
