That sucks. The ES is a great calculator. The MS is good also, but the ES was way better. As usual, the Board is way too paranoid and acting ridiculously. What else is new? It's not like you can store any answers or any kind of test information on the ES. It really doesn't do anything more than the other calculators; it was just easier to use. Sometimes, the Board really gets me frustrated, they just can't think out of the box. Here are the advantages of the ES:
--For complex numbers, you can switch back and forth easily (which can also be done with the MS). What's unique about it is that you can input the values in rectangular and polar format in the same entry. That can't be done with the MS. That was very handy for the Electrical exam.
--When you type a long entry in, and then realize you screwed up, you can take the cursor backward and forward. The other Casios do this also, I believe. The HP can't do this, I don't think, at least, not very easily.
--The display on the ES was awesome; one big dot-matrix display. Not half dot matrix, and half old-school stick figures.
Also, that HP-33 calculator is terrible. It's a piece of crap, excuse my language. That was a marketing ploy devised together by all the testing boards and HP to tap into that HP cult that holds on to the RPN stuff with their dear lives. No offense to the RPN people (honestly), but the days when RPN was faster is long gone. I challenge and continue to challenge anyone who thinks RPN is going to save any time, at least not with the type of problems on standardized exams like the PE. I understand that some people are just used to it, that's all. For $50, I was expecting much more. Take my word for it, if they banned the ES now, the best calculator --hands-down-- is the Casio fx-115ms.
I feel bad for the upcoming electrical people because that ES was so nice. I know, I'm probably making too big a deal out of it, but there was no reason to ban it. None whatsoever. This industry really gets at me sometimes. For a bunch of engineers, we sure are antiquated and old-school a lot of the time. Other people think engineers are all high-tech and use advanced technology, but I look around and laugh at it sometimes. Also, about the Board, why do they take 3 freakin months to grade a completely scantron test when the cutoff score is determined before the test is even given? Makes no sense whatsoever, and puts too much strain on people who are waiting to hear if they passed/didn't pass for the next test which is only 6 months later, which leaves them with 3 months to study, unless they start studying just in case, which is very annoying if you find out you passed.
Argh, don't get me started...
PS, when I took the EIT a few years ago, before the test started, I noticed a guy using a TI-85. I told him it wasn't allowed and he pretended not to speak English. The proctor didn't notice because she was really old. Stuff like that pisses me off. Not that I'm accusing him of storing answers on it or anything, it's just way easier to use a good calculator compared to the pieces of junk they allow now.
