Those old exams (and yes, June '95 is old) are actually a lot different from the most recent ones in terms of emphasis.
You're obviously still in improvement/learning mode, but I don't think you've solidified things just yet. That's not the state you want to be in when you record your final score. I think you should take this test in June without putting too much pressure on yourself...plan now to take it again in October and use June as a means to learn more about the actual experience and more about your weaknesses. Just relax. You don't have to worry about canceling the score...almost all schools now seem to look exclusively at the highest score. There is no rush.
