<p>Your bio score is a little low, so it’s up to you. Since I don’t know where your projection came from, I advise you to take a few practice tests (CB should have released editions) and go from there. If you consistently score beyond the 750 mark, then go for it. Otherwise, your bio score will not be result in the demise of your application (i.e. even if you are rejected, it would most likely be other reasons).</p>
