I am curious about how secure such computer-based tests are . . .
About four years ago I took a computer-based computer literacy exam
as part of a training program. I scored a 95/100 on the test. Just
to be a show off, I used a hex editor to change my score (to 100/100)
in the semi-encrypted data file and turned it in. After I was
congradulated for my great score I explained what I did, and
(fortunately) they got a good laugh out of it.
In my case, the exam was just a measure of how much extra training I
would need, so there was no significant ethical consequence of my
actions. However, in a classroom environment, a competant hacker
could get a grade with his bits rather than his wits. 🙂
Very interesting… I haven't really thought enough about possibly
altering the grades. I guess the proctor or instructor needs to keep
a watch on how the exam would be administered. I know in my
situtation, the problem would be very unlikely (small classes and
closely monitored.) Thanx for your comments. Lots to think about…
