• "Thanks. The materials and course work are excellent. Your personal instruction effort was well above average. I had been away from geology since college, 25 years, so preparation was key." G.R., Nebraska
• "Well thanks again for your study materials. I used your materials for my California PG exam last year and passed on the first try. Then last November I purchased your CEG book and flashcards. Well I passed that one too." M.T., Northern California
• "Thanks so much for the course and manual. I would surely have done poorly without them. Your course is really great and I appreciate all your hard work in putting it together." P.Z., Washington

• "Thanks for all your help. Probably wouldn't have passed without the help." N.S., Northern California

• "For the most part the course prepared me for the exam, except for some details - but if you tried to include all the details on everything, your already comprehensive course and study materials would be unmanageable. Thank you so much for creating REG REVIEW, the study materials and course were invaluable as a way of condensing an enormous amount of material into something maneageable - without them studying would have been much more difficult." A.G., New Jersey
• "I think REG REVIEW is a good solid geology course and I would recommend it. However, if future exams are going to cover the full spectrum of geological and geo-related topics to the detail that we were tested on the PG exam your will need to expand your course" T.B., Northern California
• "You two did a great job at summarizing the study manual and adding extra content that was just as relevant." T.W., Southern California
• "But all in all, I thought your review books were very helpful -- I wouldn't have passed without them. So, thank you for putting these materials together!" M.S., Southern California.
