Pearson Vue have just sent me a new 10% discount code, applicable to any VMware exam taken between now and December 15th 2010. I can give the code to any student who I train between now and then on any official VMware course.
The discount code can be used against any VMware exam, so not just the VCP4 exam, but also the VCAP4-DCA and VCAP4-DCD exams when they are released soon. The code can also be used multiple times, so if you are following the VCAP4-DCA and you still need to do your VCP4 first, you can use the code when booking each of the exams.
Note that the discount code only applies to exam bookings made directly with Pearson Vue.
