I did the Electronics Associate Practice Exam at http://www.eta-i.org/practice_exams.html
I got an 88%. 79 out of 100 questions. How many can you get?

Nice test. I got 9 wrong - accounting for the bad wording issues. The computational questions could be done in the head since the wrong answers are quite off. Also, there is quite a bit of old technology being tested - such as, a recent topic, heatsink while soldering. Overall, I´m at 85%.

Thanks for the fun. Oh, EE for the last 23 years with HAM license and a consultant.

I got 87% on my first try...........

Judging by the PC questions, I think this test IS 20 years old. For instance, there was a question about "extended memory", with the correct answer being memory over 1MB. WTF That ceased to be relevant 15 years ago. The question about EGA, VGA, XGA, etc. was dumb too; no one´s used EGA in about 18 years, and now we either go by actual numerical resolution, or things like "720p", "1080p", etc. (since most LCD monitors these days are derived from HDTVs). Now, they DID have a question about computer disk drives which mentioned SATA, so they´ve obviously updated the test in the last 8-10 years, but why´d they keep the stupid extended memory question?
There was also a bad question about some capacitors in parallel, with one of the value being 0.47 pf. That should have read 0.47 uf, or else they indicated the wrong answer as being correct.

I give this test 3 out of 5 stars. Some of the questions are pretty good, but too many of them are either just plain wrong, extremely obsolete (mainly the computer stuff), or not worded well.

I looked into becoming a CET about 20 years ago, but I changed my mind after learning that most companies have never heard of it! So I concluded it would be just a waste of time and money!! Maybe things are different today?

It was a bad question, but I disagree with the "wrong"ness of the first answer. If the proffered answer were "emits _only_ visible light when forward biased." [my emphasis] then the answer is wrong, but as stated "only emits visible light when forward biased." (note the order of the first two words) is a legitimate answer to the question.

Of course, we also know that an LED may be induced to emit light (as well as smoke and semiconductor bits) when reversed biased, too, if only for an instant. You just have to have a sufficient power source to cause it to flash into the hereafter.

There is Free Dos and DR Dos around somewhere if you need it. But considering most of code cost is maintainence you might want to leave something a little more modern for the person after you to support.
