AP Bio self study on college apps

<p>If I were to self study for AP Biology this year (senior year) and take the test in May, would that adversely affect my college applications seeing as I haven't and will not take the actual AP Biology course in school? I'm asking this especially because I want to major in pre-medicine and/or chemistry and I want to know if the actual class in school is absolutely necessary or highly recommended for college apps.</p>
