Yesterday I failed the CAS-003. I honestly felt that I passed the test, but when the final screen showed failed I was dumbfounded. I was very confident in passing this cert. I have over 20 years of IT experience. For study material, I read CompTIA Advanced Security Practitioner (CAS-003 Cert Guide Sec Edition. I did an online recording of Learning Path CompTIA Adv Sec Prac (CASP) boot camp Michael J. Shannon on Safari Books online. I used pocket prep as well and Googled things that needed additional research. Any advice from those that have passed would be great. I am so disappointed with myself as this cert is required for my job.
