So why take a mock SCJP exam test free? It is a well known fact in the IT training world that the more exam simulations you take, the more proficient you become in the IT certification area you are preparing for. By checking your knowledge and skill levels through a mock SCJP exam, you learn how you measure up in a test created by professionals in the SCJP certification standards. And if you take the mock SCJP exam under time pressure, that helps you gauge further your ability to function under time pressure using the same knowledge and skill variables.
If you prefer to use other websites for the free test exams, you may. But your advantage with Whizlabs is that they are recognized by many IT employers and IT training institutions. And recognition by your peers in the IT world does not come easy actually.
