My answer to this is . . . No.

What do I mean? First, the initial questions are
not especially important.

Sure, you can curt down on your mistakes (hence bb's advice), but you're never going to get all the way there. Even if you're scoring at the 99th percentile, you're very likely to miss quite a few questions. That's just in the nature of a computer adaptive test. What's more important is that you learn to let go on questions that aren't going well so that you have the time and energy to do well on the others. It's also important to learn from your mistakes so that you don't make the same mistakes over and over again. This isn't going to push your accuracy to 100%, or even close to that, but it will gradually push your level up.
Students often complain to me that after all the hard work they've put in mastering the material, they're frustrated that they keep missing questions due to stupid mistakes. What I say is "Welcome to the club!" I, too, miss plenty of questions due to stupid mistakes. Given my experience with the GMAT, it would be pretty bad if I were missing them because I didn't know the material! Accept a certain number of errors and don't beat yourself up about it--you can still get any score you want if your overall performance is strong.
