I am always interested to hear how my students, and now readers of my books, do on both vendor exams and future studies. If you would like to contact me and let me know how this book helped you in your certification goals, please do so. Did I miss anything? Let me know. I can't guarantee I'll answer your e-mail message, but I can guarantee that I will read all of them. My e-mail address is firstname.lastname@example.org.
