Jordan,
You mention something else that many don't take into account when complaining about the cost aspect of the seminar and how 'rich' AWS is becoming off of them. Let's run down some things:
1) The legitimate administrative cost by paid staff at Miami;
2) Shipping of seminar and exam materials to test site and back again;
3) The Conference room at the hotel;
4) Several hundred dollars worth of hand outs- codes, specs, and other materials;
5) Seminar instructor stipend, room and travel;
6) Money to the hosting section for advertising, proctoring exams, and other costs associated with the seminar;
7) Part B proctor, separate from section proctors for Parts A&C, travel, room, and stipend;
8) Exam consumables, not reusable;
9) Exam scoring and recording;
10) Mailing, emailing, of results along with certificates, wallet cards, and stamps for successful candidates;
11) Breakfast (either brought to the seminar room each morning or provided in the hotel food area by voucher or other means;
12) Lunch provided each day of the seminar (not the day of the exams).
If you were involved with the process as I have been for the past few years you would see that these exams are not quite the cash cow for AWS they are often made out to be. Is AWS making money off of them? More than likely. But they aren't getting filthy rich off of them.
When you also consider the things you will learn that, as Al said, can't be learned from online courses or self study, by personal interaction and the networking that may well start you down your career road after passing the tests because of someone you met there and developed a friendship with...How could you not gain from the time and money spent.
Sadly, too many only look at the money aspect of it. I was very satisfied with the whole experience and yes, I passed the first time through as did my son. But, I bought all the books ahead of time and was as familiar as I felt I could be before hand. I then passed the books given to me at the exam on to my son so he could start studying. We have duplicates of everything that we allow others to use in their efforts while still maintaining a set at my office.
Good luck to any planning to take the test. Just my two tin pennies worth.
Have a Great Day, Brent
