<p>I've heard that there are two different tests for computer science, A and AB. However, I only saw computer science A listed on the college board website. I'm really confused now. Could someone please explain? Thank you.</p>
<p>Computer Science AB was discontinued following the May 2009 exam administration.</p>
<p>^ very sad because most top colleges don’t accept computer science A 5 (with the exception of stanford and any others i dont know about)</p>
