<p>I am thinking about taking AP chemistry, AP physics, AP biology, AP calculus or AP statistics in high school. Would I want to repeat these classes in college so that I will understand them better and do better on exams. Is it worth taking them in high school</p>
<p>Whether or not you will be allowed to repeat those classes will depend upon the policies of your particular college. Different schools have different policies.</p>
<p>Some schools will not allow students to retake the courses they have AP scores from. Some colleges will not allow students to use AP credit no matter how well they score. Some colleges require AP scores to place into honors intro level courses.</p>
<p>Taking AP classes is beneficial regardless of whether you plan to take the exam and get college credit because it looks good on your high school transcript and it better prepares you for the hard classes that you will take in college. The problem with using AP credit for pre-med is not so much that you did it in high school (many, not all, medical schools will accept AP credit), but more so the fact that you may forget the material you learned by the time you get into college depending on what year in high school you took the course. However, it all depends on your major. If you plan on majoring in Biology, Chemistry, or BioChem, you will end up taking higher level science courses that are based on the material from introductory science courses. If you will be able to re-learn the material before your classes begin, then you may not feel the need to repeat the courses. </p>
<p>If I were to repeat any of AP courses in college, I would likely only repeat biology and chemistry. After making it through AP physics, calculus, and statistics, trust me you will not want to take it again in college.</p>
