  • BGP series, part 8: Regular Expressions

    AWESOME! My instructors wide range of experience (PMP, MSCE, Security+, CISSP, etc.) really adds to the class. She had a wonderful sense of humor and related to the audience well. Wonderful resource.Bob Hillhouse, The University of Tennessee, Knoxville
    Instructor did an excellent job. She used great analogies to make the information memorable. She also focused in on items that we should pay attention to. Loved the class!Jill Vaughan, DHS CM
    The instructor was the best teacher I have ever had at any level. I learned more in the last 7 days than I did studying on my own for the past 6 months. The material was presented in a way that was easy for everyone to understand. He by far had the most knowledge of anyone I have ever met in the subject and I hope to learn more from him in the future.Stephen Muma
    Instructor was superb in teaching this class. He used a variety of teaching styles to accommodate multiple students. He took the time to know each of us and apply his knowledge to each student specifically. Brandy Weber
