My site now has three entire SCWCD 70 questions mock exams available. All you have to do is sign up (don't worry your details will not be used for anything but the registration on that site) and the course text (about 50,000 odd words) and the mock exam questions are accessible.
All the material is aimed at the 1.4 version of the exam and is very close in style to the real exam. This is the final stretch of testing of material that has been under development for almost 18 months, so sign up while its still available without charbge and give me any feedback, comments and suggestions. See.
