CAT/CBT testing at those little centers is a terrible thing IMHO
What is actually wrong with the centuries old tradition of simple paper/papyra and some simple little tool (like a pencil) to scribe things down with?
I took the GMAT CAT WHILE in LS for some unknown reason (ok, I was bored I guess).
In the little center, after emptying my pockets and putting all my stuff into a little locker (it felt like getting booked into jail) I was escorted into a neat room with glass windows with computers all around and seated. The chair sucked and sat to low, the room was SUPER FRIGGING COLD and I looked around to try to find the sides of beef hanging from the ceiling since it was a perfect meat locker.
The terminal they put me at was RIGHT UNDERNEATH the AC output vent and it was going FULL BLAST and puring supercooled air right onto my head and body non stop. It was in late spring when it was nice and warm outside, but I was literally shivering and shaking during the entire thing and kept having to rub my hands and arms to keep them from turning blue and actually freezing up. (I am not just trying to be dramatic here, this happened). It took me about 6 hours after I left the test place to thaw out and stop shivering and to get my core temperature back to normal.
Working the mouse (total piece of $hit one that did not really work well and was really dirty too) was a pain, especially since my hands were freezing up from extreme cold, there was not much room for scratch paper to write things down and juggle all that and the chair would not adjust up to normal desk seating height, meaning that I was sitting with my head and arms well below normal desk level. Some people in the room had headphones on for whatever test and were talking out loud along with whatever they were hearing (I'm guessing it was some foreign language test), other people came and went intermittently while I was working my test and it was super distracting.
The keyboard and monitor of the PC were super cheap pieces of $hit. When it came time to type out the little graded writing thing for the GMAT at the end I had to flex and thaw out my hands over and over to even be able to frigging type. When I finished and came out of the room and was literally shaking/shivering uncontrollably (felt like frostbite was setting in), the lamo snot nosed kid (probably a freshman in college) that was 'in charge' at the time said 'you ok, test not go well?, maybe you should have studied more.' , I said "Dude, I am frozen, leave me alone and go back to your skate boarding magazine now, ok? Nice tats and your mom should be proud of the piercing you have too bro."
Anyway, pencil and paper is actually more efficient and better in many ways. Technology and computers are not the solution for everything.
Rant over for now...
At least with CBTs you don't ever have to worry about wasting time because you bubbled in answers in the wrong slots, or waste time sharpening and re-sharpening your pencils during test, or waste time on equally as ridiculous stuff. CBTs also have less noise and visual distractions since you have your own cubicle-like area with sound buffer head phones and view blockers. Moreover, CBTs tell you how much time you have left at ANY point you wish to know--so no more surprise by the 5 minute countdown. And, unlike the current paper-based LSAT, you can take the test ANY time of the year and never have to worry about late registration fees. Some other HUGE benefits: 1. You would get your score immediately, (and knowing your score immediately is extremely beneficial in determining which law schools to apply to--potentially saving you money on applications) 2. Retaking the exam would be MUCH faster. Cheating is also a step next to impossible since you have a camera recording your every move with someone watching its live feed. I took the GRE first and then the LSAT and was really in awe at how antiquated the current LSAT testing process is.
I think modernizing the test would be well worth the cost of making up more questions, (a task of which I don't think is quite as difficult and costly as you may think).
