Experience does not matter to attend SCJD certification exam.
If you have very good knowledge in Java programming (especially in Swing, Threading, RMI and Sockets) you can very well attend SCJD exam. Remember that you need to meet prior certification requirement from Oracle. Just read this article => http://www.epractizelabs.com/blog2/?p=128 .
It gives you industry standard experience in terms of design and programming since you are going to develop an application from requirements.

I am not following your logic that the more experience you have the harder it is to pass the exam. Surely the more experience you have with programming in general and J2SE in particular, the easier it is to build the application to the specification given in the assignment - which should be the key to passing the exam.
I have got plenty of experience, but I have never used Swing or NIO before [my exam allows NIO], and only had a little experience with RMI. Therefore, there was plenty for me to learn.
