It is a stupid rule that needs to be changed back ASAP for the september. Ther is no hard in having a digital timer. All proctors have to do is pace and make sure no one is cheating.
The thing about analog if you can not pace yourself.
If I had the resources and I were unethical (I am neither), I would rig a digital timer with a 2.4ghz camera and have someone go in and record images of the test. I'd sign up for the Monday test. This is probably why digital timers have been banned.
This isn't a terribly difficult thing to do. In fact, I'm surprised if people don't do this already by sticking pin-hole camera and transmitter on their persons. It's not like I saw the proctors testing the 2.4 spectrum (and that's just using off-the-shelf equipment, think of what some engineering nerds at MIT might rig up).
This might not give you access to all of the questions, but if you were able to get 1/3 or 1/2 of the answers complete questions that you then had from Sat noon to Monday to review... that's a HUGE advantage.
You could accomplish this with 1 accomplice (to take the first test) and yourself or anyone technically competent enough to make such a rigging. Total cost would be $123 for the test about about $200 in equipment. Cheaper than the powerscore books were.
Even if the tests are the same, I still wouldn't do it, ethical issues aside. Just think about how much you owe your accomplice. If your accomplice is not someone that you trust 100%--and I doubt anyone can trust anyone 100%--and if because of his/her effort you get into Harvard and land a high-power job, oh lord your accomplice can ask you for everything he/she wants. His bargaining power is certainly higher than yours. If he reports this little incidence that happened a couple years ago, you are done with life...almost.
