Does it matter what internet connection I use to take my practice test?

It may be a great idea to take the 165 question practice test at the same time and on the same day of the week you are taking the actual test.  Sometimes bandwidths are different on different days.  Remember, if you are at home to make certain other family members do not use the internet while you are taking the exam. They could cause the bandwidth to be decreased and create an unstable internet connection.
