Just discovered that LSAC updated their testing center schedule, and my local one will only be available for the December and February tests. When I last looked a few months ago, June was the only session they did not offer. As such, I've been preparing for October, and the conventional wisdom is that the earlier one applies, the better.
Unfortunately (in this context only

) I live on an island. Taking the October test will require a plane ride. The cost will not be much; in fact, it is less than LSAC's fees for opening up a non-scheduled center. My main concern relates to the consequences of travel-related stress/fatigue.
My feeling is that a good LSAT score earned in December is better than a sub-optimal October score, but this is also under the assumption that traveling to take the lsat can likely adversely affect a score.
Am I overstating the importance of an early LSAT, and thus earlier completion date? Or am I unnecessarily worried about a one hour plane ride and a taxi ride causing enough stress to lower my score?
