Generally, yes, but I will add the caveat that these exams become easier when hands-on work experience. I had no problem passing the CISSP, ISSAP, HCISPP and the CCSP with fair to minimal study because I also had extensive experience in the field.
Good luck. There is so much material out there to study and review these days that none of what we do these days makes for a difficult examination experience, when you take your time to prepare properly. I know, easier said than done.
