Dear Bwana,
I just wanted to thank you for making this course available to people with limited time at night, like me.  I 'm actually at work right now but I was able to squeeze this course in tonight.  It was painless and very informative, I really enjoyed the articles on the web site that I had been reading up on before I decided to purchase the course.  I will recommend it to everyone that is interested in the academic portion of the course.  I wish I had found your site before my recent vacation to Cabo San Lucas.
Thank you,

Dear Bwana,
This course was great, we both took Scuba in college but did not do the open water, it was terrific being able to move at a fast pace
as it was pretty much a review. It saved a great deal of time and was very well written and  I enjoyed your sense of humor.
Thanks again for a great service.

Dear Bwana,
What a terrific course.  My wife and I were delighted to have such a service.  It saved us time!  When we got to Cozumel, the dive master knew who you were.  What a small world.

Dear "Bwana"
I have finished the Scuba Lessons a few days ago, eventually getting 100% on the exam and on each of the five modules.
I just wanted to say I enjoyed the course and found a lot of the information very relevant to my diving.  I found the safety aspects of diving were really well explained, and was taught things that I didn't learn in the theory component in my own Open Water Course.  I had to answer one of the Dive Table questions in Module 5 a number of times, but this was mainly due to a calculation error rather than not understanding the principle.  I guess this is an example of "human error" and why computers are an advantage!  Thanks again for your instruction and the course.  I'm happy to report that I am a PADI OW DIVER!!
Kind regards
