| Jxam (v1.81) | Java 2 | 170 | So far best one I've tried, (and keep on using). You can tell a lot of time went into developing this, good job. The questions seem challenging and explainations are given for incorrect answers. Also, Jxam lets us choose how many questions you want on the mock exam, up to 59 for a full test. I've found this extremely useful when trying sneak in a quick 15-20 minute study session. Finally, see the Cost section, it's free. | It's bombed my JVM more than once on my Toshiba, but didn't have any problems on my old ThinkPad. Also, after a while, like most other exams, you see the same questions come up again and again. Haven't found away to get more questions into it's database. | Free |

| JDCert | 1.1, Java 2 | 65 for 1.1, 66 for Java 2 | Looks like you can provide your own questions, but doesn't explain how. | Majority of explaination for wrong answers are: "No explanation available"
