<p>Could I just take the CS ap exam with out any studying besides knowing C++ pretty well? could i score a 4 or 5 with that?</p>
<p>No, the ap exam tests your knowledge of Java, not C++.</p>
<p>Java should be fairly easy to learn though, considering you are pretty good in C++. I’d recommend familiarizing yourself with Java by writing a few basic Java programs, then reading Barron’s book to familiarize yourself with the exam. From there, you should easily be able to pull a 5.</p>
