<p>Im not sure, I really dont know much at all about the AB/ScB. Yes, it is possible to graduate early, you have to do 4 summer session courses (that means at least 2 summers, because the coursload is 1-2 per summer) for 1 semester reduction. </p>
<p>Dont count on finishing in 4 years, if so few people do it, and they say 5 years, I doubt that people do it in 4. </p>
<p>Why are you set on AB/ScB anyways???</p>
