Can't vouch for the successfulness yet (taking my test in 8 days). However, I was not very enamored with Chemerinsky as a study guide. Unless you've been working with it along with the class it simply doesn't function as an effective study aid. I actually like the examples and explanations for Con Law (the national powers one) and have also been using the Emanuel Crunchtime. My class didn't spend much time on individual rights so I'm not as worried. But seriously, at this late day trying to deal with Chemerinsky is just a bad idea - learn how to apply the law and argue in different directions, don't just read another textbook.
